Up until about two weeks ago it was developed on Win2k sp2, now I'm on XP.
The calling code gets run 1000+ times per run, and has run without issue on
several hundred (perhaps a thousand) machines.  It gets run on
Win9X/Me/NT/2k/XP all generally without issue.

I'm not familiar with 'error 11', what is that?  Compiling w/ various
optimizations is my next step.  The only saving grace is that it is
consistent in where it throws the exception.  I have eyeballed the code and
attempted to duplicate it and the code looks fine (both mine and libxml) and
any attempts to duplicate it have failed.

Bizarro!
