guile-1.8.8 problem on GNU/Linux IA-64 and a simple fix

guile-1.8.8 problem on GNU/Linux IA-64 and a simple fix

[Nelson H. F. Beebe]

I built guile-1.8.8 on GNU/Linux IA-64 (Itanium) like this:

% env LDFLAGS='-L/usr/local/lib -Wl,-rpath,/usr/local/lib ' CC=/usr/bin/gcc ./configure
% make LIBS='/usr/lib/libreadline.so /usr/lib/libncurses.so' all check -i -k -s

and got this single failure:

Running time.test
/bin/sh: line 5: 26260 Segmentation fault      ${dir}$tst
FAIL: check-guile
==================================
1 of 1 test failed
Please report to bug-guile@gnu.org
==================================

On a hunch, I tried this:

% limit
cputime      unlimited
filesize     unlimited
datasize     unlimited
stacksize    10240 kbytes
coredumpsize 0 kbytes
memoryuse    unlimited
vmemoryuse   unlimited
descriptors  1024
memorylocked 128 kbytes
maxproc      8110
maxlocks     unlimited
maxsignal    8110
maxmessage   819200
maxnice      0
maxrtprio    0
maxrttime    0 usec

% limit stacksize 100M
% make check -i -k -s
...
Running time.test
Running unif.test
Running version.test
Running weaks.test

Totals for this test run:
passes:                 11972
failures:               0
unexpected passes:      0
expected failures:      24
unresolved test cases:  9
untested test cases:    0
unsupported test cases: 9
errors:                 0

PASS: check-guile
=============
1 test passed
=============

It looks like the time.test run is stessing the default stacksize.

Perhaps the test suite could increase that limit, or better, the test
might be adjusted to run in 8MB or so of stack space.  On one of my
systems (OpenBSD), the default is 4MB; several others have 8MB, a few
10MB, and a couple, 64MB.

Are you building with -O2 or O0?  AFAIK, the whole 1.8 branch has bad
stack behavior with -O0...

However, as IA-64 is an uncommon platform, and 2.0 will be out soon
(which AFAIK does not exhibit this problem), I would be inclined to let
search engines pick up the workaround from these mails.

Let us know if there is something else we should do.

Thanks for the report,

Andy
