Scott Cantor commented on XERCESC-2179:
---------------------------------------
The problem is not in the variable you added that comment about in the patch.
I believe the bug is in that second set of parameters at the end where it
passes in the wrong value for the size of the "theSize" variable that was set
to 4 bytes in the code. But I don't understand that well enough to be certain
what I'm seeing yet.
The comment in the patch was confusing this discussion because it's referring
to a change from unsigned long to DWORD, and that is not a change. It's not
theType that's causing trouble, but theSize.
