segfault when using PerlRequire
I hesitate to post this because I haven't kept up with my reading. I did
do several searches of my 28K message modperl mail folder and the list
archives.
My httpd.conf reads...
LoadModule perl_module /opt/apache/libexec/libperl.so
#PerlModule Apache::Status
PerlRequire /home/stevens.1/apache-perl/conf/startup.pl
If I uncomment the PerlModule config, then no core dump.
If I downgrade to perl-5.0.3, then no core dump.
If I Configure -Uuselargefiles, I still core dump.
Solaris bug, Perl bug, modperl bug, Apache bug, or driver error?
Thanks,
John

I assume that you use Apache DSO. I think that you need to rebuild your
perl with -Ubincompat5005. I cannot see the value of bincompat5005 in
your 'perl -V'
