In general, Perl should never dump core - it's very bad. Specifically
here, though, it should be a minor issue. I have seen this type of
problem happening on some installations, and have never been able to
debug the issue. 

See if you can write the programs you want to write, and if so, you

The UNIVERSAL docs in Perl 5.6 say "These subroutines should not be imported via
use UNIVERSAL qw(...)", while the docs in 5.8 positively encourage you to do so.
So it may be the case that this is only a problem in 5.6 and not in 5.8. I
haven't tested yet, but if someone does get the chance to do a test in 5.8
please post the results here.

I recently spent an entire morning debugging a similar problem caused by 'use
UNIVERSAL' in a program which also relied on a C++ XS extension.  The
application simply bailed out with a coredump.

Not related to Xerces, per se, but perhaps an indication of a Perl problem. 
This was noted with perl-5.8.0 on both x86 Linux and 32-bit AIX.

[Ian Douglas] XML::Xerces

Favicon
From: Ian Douglas <id <at> pricegrabber.com>
Subject: XML::Xerces
Date: 2005-04-26 18:55:40 GMT
Hi Jason,

Trying to build XML::Xerces, and downloaded the 2.5.0 archive from 
xml.apache.org. The only build of Xerces-C (listed as a requirement) is 
2.6.0, so the Perl module fails.

Any advice on where I can get Xerces-C 2.5.0 so I can compile the 
XML::Xerces library, or do you have a 2.6.0 version of the Perl code?

Perhaps I should ask this as well: will Xerces allow me to validate a 
pre-built XML feed if I have an XSD file from the client to whom I'd be 
sending my XML feed?
