I was able to reproduce this problem on x86 and x86_64 systems (with different
symptoms on each :-).  It's caused by some coding within xmlschemastypes.c,
and may occur anytime the total number of digits in the number exceeds 10. 
I'm working on a "proper" solution for it, but it may be a day or two before I
can complete it.  I'll let you know when the fix is complete.
