Subject: mod_perl under 5.10 SEGV
Since last night PAUSE is running under 5.10-RC2. With
MaxRequestPerChild set to 1 I get a SEGV after every request. Users
seem to not be affected. Unfortunately I built without -g, so the
backtrace is a bit thin. I'll re-do with -g in the evening.

That function comes from mod_perl.
av_undef() can't be passed a null array; an assert() has been added as
change #26513. Maybe just a check should be added to perl_shutdown ?
(What version of mod_perl are you using ? I can't locate that av_undef
in the code)

Sorry, I should have been paying more attention to this thread. I fixed
this in mod_perl back in July (although mod_perl-1.31 hasn't yet been
released so it's only in svn):

http://svn.apache.org/viewvc?view=rev&revision=555908

Thanks for the pointer Steve, I'll give it a try.

Works nicely. Now also uploaded into my CPAN directory as
ANDK/mod_perl-1.30-SHAY-01.patch.gz

PAUSE is now running with bleadperl@32603.

Thanks,
