I will preface this message with this: this is not a mod_perl bug or
problem, but it involves a mod_perl application, so this is probably a
good place to get advice from experienced mod_perl users/developers.
I have an application that ran on mod_perl 1.3 and perl 5.8 for a long
time, that I recently ported over to a Fedora 9 box, thus moving it to
mod_perl 2.0 and perl 5.10.
Under this new environment, I am getting some of the most bizarre and
insidious perl core errors I've ever seen in my 15 years of using perl.
Here's a sampling:
Attempt to free unreferenced scalar: SV 0xbd266be4, Perl interpreter:
0xba01c410 at /usr/lib/perl5/vendor_perl/5.10.0/HTML/Mason/Component.pm
line 147.
panic: attempt to copy value 20 to a freed scalar bd49dffc
Use of freed value in iteration
panic: free from wrong pool
Not to mention countless application errors involving dereferencing,
where things that are supposed to be arrays and hashrefs have magically
turned into strings and key values, and vice versa.
For what it is worth, I spent a couple hours trying to a development
setup running on FC9 with 5.10.0, and gave up because of oddball errors.
Perl 5.10.0 is considered to be a testing release
(http://cpan.perl.org/src/README.html), and FC9 is still pretty fresh.
I would suggest going with FC8 and 5.8.8 until FC9 has been out in the
wild for a while, and perhaps waiting until 5.10.1 is released. You may
be able to figure out exactly what the problem is, but it may make more
sense to use FC8 and 5.8.8.
