Description

This issue just happens on Solaris 10 x64. There is no problem on other platforms, such as Solaris 10 x86 (32-bit), AIX (both 32 and 64), HP-UX (both PA-RISC and IA64), Linux x86 etc.

I wrote a xerces-c sax application on Solaris 10 x64. The class "MXmlHandler" was the xml handler what was inherited from "DefaultHandeler".

The following is the compiler and linker flags.
Compiler flags: -mt -xarch=amd64 -g -I/usr/app/xercesc/2.8/include
Linker flags: -mt -xarch=amd64 -L/usr/app/xercesc/2.8/lib -lxerces-c

At the begining of the method
void startElement( const XMLCh* const uri,
const XMLCh* const localname,
const XMLCh* const qname,
const Attributes& attributes);

the value of the parameter "qname" was wrong. For example the qname should be a string like "schemaName", but it was a recognised string. This is the behavior in RELEASE libraries. In the DEBUG mode, the application crashed in xerces-c libraries.

The following is traceback.
