Segfaults with RH6.1, mod_perl, perl 5.6.0, and apache 1.3.12

[Benjamin Reed <ra...@befunk.com>]

I'm getting segfaults with a RedHat 6.1 system.  I've tried mod_perl 1.22,
as well as a CVS snapshot from today, and I pretty much get the same thing
either way.  I would appreciate it if anyone could help me out on this, it's
driving me nuts.

Here's my system:

RedHat 6.1 (with all updates)
Apache 1.3.12 (compiled myself after having this happen with the rh-default
apache)
mod_perl 1.22 (and 1.22-dev, same thing either way)
perl 5.6.0 (perl -V says:)

Any ideas what's going on here?  Thanks for any insight you can give.

does 'make test' pass for you?  if so, we'll need more details on what
your server is doing, e.g. using XML::Parser?
