Summary: XML::Parser::parse() segfaults mod_perl

Initial Comment:
Versions:
  FreeBSD 4.2-STABLE
  Apache 1.3.17
  mod_perl 1.25
  perl 5.00503
  XML::Parser 2.30
  expat 1.95.1
  opensrs-client 2.3.2

When used under mod_perl in the environment described, a call to the parse() method in an 
XML::Parser object causes the Apache instance to segfault.  This is in context of the OpenSRS 
client communication library, which uses XML for its protocol.  Everything is fine when the same 
code is used as a standalone CGI.

I ran into this same problem on Linux. By compiling Apache 
without expat, parse() now runs fine in XML::Parser. I ran 
Apache's configure with the 
--disable-rule=EXPAT
option.

Of course, the implicit assumption here is that other parts 
of Apache are OK not having expat-lite installed.....

I have the same problem on a solaris box. I think fdrake has
made a correct diagnosis. Apache contains 'expat-lite' and
there seems to be a namespace collision when you load expate
via Perl::XML under mod_perl.

I am not sure what the solution is.

I *think* you're getting two copies of Expat linked in, but I'm not sure.  Essentially, Apache/mod_perl might have one, and XML::Parser can also have one.

I'm assigning this to Clark since the Perl bindings are his baby.
