Environment: All platforms
Description:
I may be misunderstanding how this should work, but
GrammarResolver::resetCachedGrammar() clears the associated XMLGrammarPool instance,
but does not clears its own cache of pooled grammars, stored in the member variable
fGrammarFromPool. The result is a dangling pointer to a Grammar instance that no
longer exists. I've applied the following patch to my local copy of Xerces-C, which
seems to clear up the problem.
cvs diff GrammarResolver.cpp (in directory
V:\xml-xerces\c\src\xercesc\validators\common\)
Index: GrammarResolver.cpp
