Compatibility with Itanium Processor Machines

I am currently using Xerces 2.2.0 on both a Pentium and an Itanium machine with
Linux. I have made a program, identical copies of which are on both machines,
that must parse a document with a line similar to the following:

<xmlTag abc:dataLocation="http://www.whereTheDataIs.org
../directoryDoesNotExist/file.txt">

Where "directoryDoesNotExist" is a non-existant directory, as you can likely
judge from the name.

On the Pentium machine, I receive the following expected warning:

XML error: An exception occurred! Type:RuntimeException, Message:Warning: The
primary document entity could not be opened.
Id=/home/userID/directoryDoesNotExist/file.txt at line: 0

On the Itanium machine, however, using the exact same code, directory
structure, etc., I only get a segmentation fault. Has compatibility of Xerces
with Itanium processors been examined?

(Sorry, I initially accidentally posted this for the Java version)
