Summary: Segmentation fault on UTF-8 BOM

Initial Comment:
It appears that expat will crash when parsing any 
document that begins with a UTF-8 BOM (0xefbbbf).  
When initScan() sees this sequence of characters at 
the beginning of a document, it does not set 
*nextTokPtr, so the next iteration of prologProcessor
() uses a bogus pointer, ultimately causing a crash.

This could be related to bug #214050 (Segmentation 
fault in libxmltok).

What version were you using?  I checked in a fix for a problem matching this description since the 1.95.1 release.  Can you reproduce the bug using the CVS version of Expat?

Thanks.
