Subject RE: Crash in XercesHandler.cpp with & in response
Date Tue, 16 May 2006 08:20:44 GMT
Hi,

As we've now excluded the illegal use of '&', it could be related to how
the SOAP message is being received, I know of some bugs fixed in 1.6 which
could cause similar problems to those you describe.
Is it possible for you to attach the "on-the-wire" SOAP/HTTP message
causing this problem?

Thanks,
Adrian
