Subject Re: AW: Strange problem with pattern (Xerces 2.5.0 crashes)
Date Thu, 15 Apr 2004 10:50:55 GMT
Hi,

	I have reproduced this problem. I can make the working one break
just by adding a "test" element before the body. I will review the code
and see if I can see anything, but I doubt this is going to be a 2 second
fix.

Cheers,

Gareth
