boehm-gc troubles with 2.0.10 on NetBSD/i386

boehm-gc troubles with 2.0.10 on NetBSD/i386

I've been a guile user erratically for a long time, and maintain the
entry for guile in pkgsrc.  Currently that's at 1.8.8 and it works fine.

There's a draft package for guile 2.  boehm-gc in pkgsrc on NetBSD is
built without threads, and I have --disable-threads passed to guile's
configure.

The build goes ok until trying to run guild.  Just starting it without
args leads to:

/usr/pkgsrc/wip/guile2/work/guile-2.0.10/libguile > ../meta/uninstalled-env ../meta/guild
0xbbbe12d4 is not a GC visible pointer location
GC_is_visible test failed
Abort trap (core dumped)

Trying with gdb:

Starting program: /u0/n0/gdt/NetBSD-current/pkgsrc/wip/guile2/work/guile-2.0.10/libguile/.libs/guile

When I run the included tests on boehm-gc 7.2e, they all past.


So I wonder if you think this is a boehm-gc issue, or something odd that
guile is doing to boehm-gc.  Any hints would be appreciated.

As documented in our README and the output of ./configure --help,
"--without-threads" is the option you should be using.  To be honest,
I'm not sure what "--disable-threads" will do, if anything.  It's
possible that gnulib is somehow enabling that option to be accepted
without an error.

Also, please don't use Guile 2.0.10.  It was a brown-paper-bag release.
Please use Guile 2.0.11, which was released 3 days after 2.0.10.

The relevant code is in gc.c line 632, which verifies that the GC can
see the static variable 'scm_protects' defined in the same file.  If it
can't, that indicates a serious problem with the garbage collector.

Before I investigate this any further, can you try with Guile 2.0.11 and
passing "--without-threads" to ./configure?

      Mark

Thanks for looking at my issue.

Sorry, I typed that from memory.  It was --with-threads=no and I changed
it to --without-threads.  My configure output shows:

checking what kind of threads to support... null-threads

OK; I've updated the package to 2.0.11.  I now remember noticing that.

After fixing the --disable-threads and updating to 2.0.11, I get the
following.  I'll ask pkgsrc/netbsd people about libgc, since that seems
to be the issue.

I realize this packaging control file is a foreign language, but here's how it looks:

  .include "../../mk/bsd.pkg.mk"


So really guile is building pretty close to natively.

My guess is that this SIGSEGV is probably intentional, perhaps the
method used by GC on NetBSD to determine the bounds of the stack or some
other data area.  I would try continuing and seeing what happens next.
GC may also use some other signals for its own purposes.

I think this license field is incorrect.  Guile's license is the GNU
_Lesser_ General Public License v3-or-later.

continuing leads to the program exiting.  I should build libgc with
debugging...

Is everything that is installed under LGPL, even readline?
(But even if so, that should say "gnu-gpl-v3 AND gnu-lgpl-v3".)

In an earlier message, you wrote that guild prints the following when
run normally:

> /usr/pkgsrc/wip/guile2/work/guile-2.0.10/libguile > ../meta/uninstalled-env ../meta/guild
> 0xbbbe12d4 is not a GC visible pointer location

Does this not happen when running it within GDB?

It would be good to try building with -g and -Og or -O0, and perhaps
also installing a more recent version of GDB.

While helping someone working on getting Guile 2 into FreeBSD ports, I
learned that FreeBSD includes a very old version of GDB, presumably to
avoid the GNU GPLv3.  We also learned that recent versions of GDB show
function arguments in the backtrace whereas the GDB included in FreeBSD
apparently doesn't.  Perhaps the situation is similar on NetBSD.

The Guile distribution includes an optional 'libguilereadline' library,
which links with libreadline and is covered by GNU GPL v3-or-later.  It
is not used unless explicitly loaded by the user.  Guile itself is
covered by GNU LGPL v3-or-later.

As for all unrecognized options, ./configure prints a warning and
ignores it.

Greg, does libgc’s own ‘make check’ pass on this platform?

I am using gc-7.2e, which is what pkgsrc has, and which
  http://www.hboehm.info/gc/
indicates is the latest stable version.  This is with gcc 4.5.3 on i386.


ludo@gnu.org (Ludovic Courtès) writes:

> Greg, does libgc’s own ‘make check’ pass on this platform?

Yes.  libgc seems to have multiple tests.  pkgsrc has the following, and
it runs fine:

do-test:
        cd ${WRKSRC} && \
        ${RM} -f gctest && ${MAKE_PROGRAM} gctest && ./gctest && \
        ${RM} -f test_cpp && ${MAKE_PROGRAM} test_cpp && ./test_cpp 10

also, cding into the build directory after the package is built and "gmake check" passes.


gory details in case it matters, make test (above taret) and then check:

Re: boehm-gc troubles with 2.0.11 on NetBSD/i386

A partial update:

  I am using 2.0.11 now.

  After updating to libgc 7.4.0, I have the same problem with a similar
  stack trace.  libgc is built without threads and passes it's "gmake
  check".

  I have the same problem with libgc 7.4.0 on netbsd-5/i386 (libgc
  passes gmake check on this combination also).

  On netbsd-5/i386, I tried to build libgc and guile with threads, but
  it failed to link with tls_get_addr.  This is likely a known lack of
  support in netbsd-5 which AFAIK doesn't provide thread-local storage.

  I haven't yet compiled libgc and guile with debugging symbols and
  without optimization; I realize that's what I need to do to figure
  this out.  I read a bit of the code to get started understanding the
  boot sequence.

  It seems there is detection of stack growth detection.  I wonder if
  that's somehow going astray.

I am curious if others are having success on other *BSD, and which
versions and architectures.

2.0.11 was fine on OpenBSD 5.3 amd64 AKA x86_64, with libgc 7.4.  (Sadly
I'm not on OpenBSD anymore so in case you have detailed questions I may
not be able to answer them.)

OS X 10.9 is also mostly fine, though with some issues.  See relevant ML
thread, "2.0.11 on OS X 10.9 / Xcode 5.1".

zacts on #guile has done work on a guile 2.0.11 package for FreeBSD
ports, and based on his reports it seems to work well.  IIRC, he built
it (and boehm-gc) with threads enabled (pthreads).  There was just one
notable issue: guile needs a patch (see attached) for clang 3.4 on
32-bit systems.  I haven't yet pushed this to git because it needs to be
made more portable.  Anyway, I doubt it's related to the problem you're
seeing.

First, can you verify that you have the following patch applied?

  http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commitdiff;h=156119b0223cf14d335ebda84701a69b2ba95757

It was not in 2.0.11 and is needed for 32-bit clang builds.
