bug#28181: 26.0.50; emacs master segfaults on make-network-process, embedded device nokia n900

[rrandresf]

The problem is with emacs master.

"emacs -Q" and M-x eww "f1aldia.com" segfaults emacs.

the segfault happens on make-network-process (process.c) 

The same works fine on emacs-25.2 on the same device

It doesn't segfault for me.  I see your build is 2 months old, so
could you please re-sync with upstream, build the current master, and
see if the problem persists?  If it does, please show a C-level
backtrace from the crash (you will need to build Emacs without the -s
switch in CFLAGS, to prevent stripping of the symbols, without which
the backtrace is not useful).

Thanks.

Yes.  I would suggest -g3, though, not just -g.

By "same backtrace" do you mean GDB again says "no symbols"?

Did you install the built Emacs, and if so, did you perhaps use "make
install-strip" to do that?

Yes.

No.
this is the complete procedure:
1. git clone --depth=1 https://github.com/emacs-mirror/emacs (on a quicker machine)
2. autoreconf -i -I m4 --force; make bootstrap; ./make-dist --snapshot --no-compress --no-changelog
3. compile on embedded device (with tar generated on step 2)
CFLAGS="-g -O0" ../configure --without-gconf --with-xft --without-xwidgets --with-xpm=no --with-gif=no --without-selinux --disable-acl --with-gnutls=no --with-x-toolkit=no --without-pop
make
4. gdb --args ./src/emacs -Q

I remember a similar problem with the stack (on another device) with a postgres odbc
driver. It fixed with a new glibc version. So probably libc version is
the reason:

Then how do you know the problem was in process.c?  The backtrace
you've shown stops before it gets to Emacs sources.  Maybe try "thread
apply all bt" instead of just "bt", you may have shown backtrace for a
non-main thread.

I edebbugged it. then gdbbed it

started from the eww function
url-retrieve
url-retrieve-internal
url-http
[...]
make-network-process (i put a breakpoint there too)
when entering make-network-process the segfault happened.

OK, but please try the GDB command I proposed anyway, once Emacs
segfaults.  It might show important additional information.

ulimit, if you have it there.

Doesn't necessarily mean anything.

In any case, the backtrace shows the problem didn't happen in
process.c.

Can you show exactly what GDB says at the moment of crash?  I'd like
to see the full text of the message about the fatal signal.

after segfault i did bt on gdb. And I sent it on the bug report
'xbacktrace' is not supported on this gdb version.

Do You need any other command to apply on gdb?

Strange.

It's not a command.  When a program running under GDB crashes due to a
fatal signal, GDB says something like this:

  Program received signal SIGSEGV, Segmentation fault.
  set_glyph_string_background_width (s=0x838aca0, start=1, last_x=665)
      at xdisp.c:19970
  19970	  if (start == s->row->used[s->area]

I would like to see these few lines in your case.

Thanks.

So this indeed looks like some libc problem, and therefore I don't
think it's a problem in Emacs.

Thanks.

I am going to try to find the commit that causes the issue. That could
help making a workaround, but probably just for this embedded
device. Could It be a good idea?

I'm almost sure that the problem is with getaddrinfo_a, which we now
use on platforms that provide this function.  Maybe you could tweak
the build to not define HAVE_GETADDRINFO_A, and see if that makes the
problem go away.

Below line should do the job?:

No, I think you need to say this:

  ac_cv_lib_anl_getaddrinfo_a=no CFLAGS="-g3 -O0" ../configure --without-gconf --with-xft --without-xwidgets --with-xpm=no --with-gif=no --without-selinux --disable-acl --with-gnutls=no --with-x-toolkit=no --without-pop

You were Right Eli. It did not segfaulted.

I have another question. As my embedded device has a debian based
distro. This is what I have on the debian/rules file:
--8<---------------cut here---------------start------------->8---
 ./configure $(CROSS) --prefix=/usr --mandir=\$${prefix}/share/man --infodir=\$${prefix}/share/info --without-gconf --with-xft --without-xwidgets --with-xpm=no --with-gif=no --without-selinux --with-gnutls=no --without-pop --without-pop --disable-acl CFLAGS="$(CFLAGS)" LDFLAGS="-Wl,-z,defs"
--8<---------------cut here---------------end--------------->8---

How should I acommodate the expression below on my configure line?
--8<---------------cut here---------------start------------->8---
ac_cv_lib_anl_getaddrinfo_a=no
--8<---------------cut here---------------end--------------->8---

bug#28181: 26.0.50; emacs master segfaults on make-network-process, embedded device nokia n900

packaging also solved with this line on debian rules (for packaging on my debian based distro):

In that case, one more check: the getaddrinfo_a function AFAIK lives
in the libanl library.  You should be able to see that the Emacs
binaries you've built before, those that segfaulted, depend on that
library, by running ldd on the binary.  So do you have that library
available on that device?  If not, that could perhaps be the reason
for a segfault in the normal build.

OK.  So can this bug be closed, or is there anything else left to do
about it?
