Hi, I've been trying in vain over the last day or so to reproduce the following GHC bugs, both allegedly demonstrated by Pugs: [ 1226252 ] internal error: EVACUATED object entered! http://sourceforge.net/tracker/index.php?func=detail&aid=1222522&group_i d=8032&atid=108032 [ 1222522 ] scavenge_stack: weird activation record found on stack:37548 http://sourceforge.net/tracker/index.php?func=detail&aid=1222522&group_i d=8032&atid=108032 I checked out the exact revisions using SVN as specified in the bug reports, and I've tried various combinations of {1386,x86_64}, {Linux,FreeBSD}, {GHC 6.4, 6.4.1-STABLE}, {optimised,unoptimised}. I do indeed get test failures for the t/oo/desctruction.t test, but no crashes. For example, on the FreeBSD/x86/optimised build I just did: ~/local/pugs > GHCRTS=-H1m PERL_DL_NONLAZY=1 /usr/local/bin/perl "-I../../inc" "-I../inc" "-Iinc" "-MExtUtils::Command::MM" "-e" "ENV->{HARNESS_PERL} = q{/home/simonmar/local/pugs/blib/script/pugs}; @ARGV = map glob, @ARGV; ENV->{PERL6LIB} = q{/home/simonmar/local/pugs/blib6/lib}; test_harness(0, 'inc', '/home/simonmar/local/pugs/blib/lib', '/home/simonmar/local/pugs/blib/arch')" t/oo/destruction.t t/oo/destruction....NOK 5# Looks like you failed 2 tests of 6 t/oo/destruction....FAILED tests 4-5 Failed 2/6 tests, 66.67% okay Failed Test Stat Wstat Total Fail Failed List of Failed ------------------------------------------------------------------------ ------- t/oo/destruction.t 6 2 33.33% 4-5 Failed 1/1 test scripts, 0.00% okay. 2/6 subtests failed, 66.67% okay. I can vary the success rate by altering GHC's garbage collector options (e.g. the GHCRTS setting in the command above). At this point I'm stuck. I don't doubt there's a bug somewhere, but it's not showing itself for me. If someone can provide me with a temporary account on a machine that demonstrates the bug, that would be great. SSH key available on request. Even better if you could set me up with an account and a Pugs build tree all ready to go. I've spent too much time on this to give up now! Cheers, Simon
