Apache core dumps on loading mod_perl
Hi all,
using perl-5.8.5, apache 1.3.x and mod_perl 1.29, I'm getting a core dump
when libperl.so gets loaded via LoadModule perl_module path/libperl.so.
Does the following gdb stack trace ring a bell with anyone?

This is a well kown issue.
ITHREADS are just not going to work on the 4.x series... You'll have to
upgrade to at least 5.3.. Likely 5.4. I'd really recommend
reinstalling from scratch or doing a bin upgrade as I don't think you'll
be able to cross the 5.2.1 -> 5.3 boundrary do to signifigant changes in
the build process internals. Other option is to compile perl without
ithreads. It will be siginifigantly faster anyway.
If you straight upgrade via /usr/src, make sure you edit
/etc/libmap.conf
to link against libpthread.so instead of libc_r.so
Given this new insite, this core dump now makes sense:
#4 0x2062e7aa in ioctl () from /usr/lib/libc_r.so.4
BOOM!
P.S.
If you haven't guessed, I'm a FreeBSD contributor and bin fan :)
Had I read it closer, I could have guessed you were on FreeBSD pre SMPng!

No, I was just pointing out that the coredump happened in the PerlIO
routines..... If you need it, then I guess that plan won't work.

Are you saying that mod_perl 1.29 requires perl to be compiled without
perlio? My perl needs ithreads/perlio, so that would be a problem. Here's
the relevant part of perl -V (sorry, can't post all of it):
usethreads=define use5005threads=undef useithreads=define
usemultiplicity=define
useperlio=define d_sfio=undef uselargefiles=define usesocks=undef
use64bitint=undef use64bitall=undef uselongdouble=undef
usemymalloc=n, bincompat5005=undef

Try compiling your perl without PerlIO
Configure -Uuseperlio
In the future, send a perl -V
or better yet,
