Re: Segfaults when using XML::Parser
I have found this section under the "Warnings and Errors Troubleshooting"
on the web site. It states:
If you have some of the processes segfault when using XML::Parser you
should use
--disable-rule=EXPAT
during the Apache configuration step.
Starting from mod_perl version 1.23 this option is disabled by default.
It is unclear to me where this disable-rule is specified. I would assume
in apache, but then it makes a statement that the option has been disabled
by default for mod_perl 1.23+. That seems to imply the option is in
mod_perl?
Can someone please give me specific information about how I would go about
using this disable-rule to fix the afformentioned problem.
Can someone also give me some information on why this is needed to fix the
problem...what is the root cause of this problem? I have only ran into
this problem on my fully updated RedHat 7.3 box (apache 1.3.23 & mod_perl
1.26), not my RH 6.2 (apache 1.3.12 & mod_perl 1.24) boxes. Please
advise.

Thanks. I found that I was using a custom apache build without that
enabled, but it is fixed now with a newer apache RPM for redhat.
Thanks again.

In the configure line for Apache, like so:
./configure --disable-rule=EXPAT \
--activate-module=src/modules/perl/libperl.a

That's assuming you have the mod_perl distribution build Apache for
you, not if you're doing it the other way around.

The above should help.

XML::Parser doesn't hide it's symbols properly and hence they collide
with the expat-lite that's in Apache by default. I can't believe this
hasn't been fixed by now.
Nonetheless, this subject has been covered over and over on the list.
If you look in the archives you'll most certainly find more details.
