guile 1.8.3 fails to build on sparc

[Kamaraju S Kusumanchi]

I don't have access to sparc machine to probe into this problem. Can someone
look at
http://buildd.debian.org/fetch.cgi?pkg=guile-1.8;ver=1.8.3%2B1-1;arch=sparc;stamp=1195798674
and see why guile-1.8-libs fails to build on a sparc machine?

thanks
raju

Another build failure of guile-1.8.3 on alpha

http://buildd.debian.org/fetch.cgi?pkg=guile-1.8;ver=1.8.3%2B1-1;arch=alpha;stamp=1196201747

Sorry this response is so delayed.  Seems to be a GC issue:

FAIL: gc.test: gc: Unused modules are removed

I'll take a look.

And this one is strange:

Running r4rs.test
ERROR: Wrong type to apply: (#0# . #0#)
FAIL: check-guile

No idea right now, but will investigate...  Is it possible to use
buildd for exploratory tests - I'm guessing not.  Does someone have an
alpha box, and if so can you reproduce this problem with Guile 1.8.3?

In case this helps:
I did a build of guile 1.8.3 from pkgsrc on NetBSD/sparc64.  It built
and the resulting guile worked.  I ran 'gmake check' and it seemed to run fine.

Totals for this test run:
passes:                 11862
failures:               0
unexpected passes:      0
expected failures:      25
unresolved test cases:  12
untested test cases:    0
unsupported test cases: 11
errors:                 0

PASS: check-guile

FWIW, I have a sparc64 box and I noticed the problem long ago but was
essentially too lazy to fix it (I seem to recall that I blamed the test
case back then ;-)).

I'm pretty sure it's a boring problem, like a dangling reference to a
module kept on the stack.  I'll try to look into it.

Thanks,
Ludovic.

AFAIK, only debian developers get access to the buildd machines. If you know
of any debian developer then you can ask them for an account.

This indeed looks like a reference to a single module is kept somewhere,
e.g., in an area of the stack that was not overwritten by subsequent
calls, leading to the wrong object count.

Adding a function call right before the first `(gc)' sometimes fixes the
problem, sometimes not.  The attached snippet reliably fixes the problem
on my GNU/Linux sparc64 box, though.

Rob: Would it be possible for you to try out this patch on one of the
Debian SPARC machines?

Thanks in advance,
Ludovic.

It looks like that doesn't fix the problem -- it failed on ia64 this
time:

  https://buildd.debian.org/status/fetch.php?pkg=guile-1.8&arch=ia64&ver=1.8.8%2B1-7&stamp=1323288478

The bug also appears to affect Guile 2.0 on kfreebsd-i386, s390, and
perhaps others (some archs won't build 2.0 at all yet) see the "last
log" links here:

  https://buildd.debian.org/status/package.php?p=guile-2.0&suite=sid

i.e., for the gc.test problem on kfreebsd-i386 and s390:

  https://buildd.debian.org/status/fetch.php?pkg=guile-2.0&arch=kfreebsd-i386&ver=2.0.3%2B1-2&stamp=1322025585
  https://buildd.debian.org/status/fetch.php?pkg=guile-2.0&arch=s390&ver=2.0.3%2B1-2&stamp=1322025002

Anything else I might try?

Hi Rob,

“Unused modules are removed” and similar tests seem to depend on the
direction of the wind, unfortunately.  So for now you can safely ignore
them, by adding (throw 'unresolved), or commenting them out.

I’m afraid we cannot do much better on our side.  :-/

Thanks,
Ludo’.
