After transcode, delete bombs in dll

[James Pearson <ja...@computer.org>]

Hi All,

I hope this isn't too dumb a question: does Xerces have special
"considerations" when it's run from within a DLL?

A bit of background:
I'm using the 1_2_0a release of Xerces, built with MSVC++ 6.0SP3 using the
supplied debug version project files on Win2000 Professional. The code is
compiled into a DLL.

The Problem:
When I run the following code (which is in the dll):

	if( str.equals("TaskName") ){
		char* str = cNode.getNodeValue().transcode();
		strcpy( m_TaskName, str );
		delete [] str;                        <<== bombs out here
	}

The error I get when it tries to execute  "delete [] str;" :

Debug Assertion Failed!
File: dbgheap.c
Line: 1011
Expression: _CrtIsValidHeapPointer(pUserData)

The top of the stack (for what it's worth) looks like:

NTDLL! 77f9f9df()
NTDLL! 77fb4966()
NTDLL! 77f8b3d2()
KERNEL32! 77e944cd()
_CrtIsValidHeapPointer(const void * 0x0093a830) line 1606
_free_dbg_lk(void * 0x0093a830, int 1) line 1011 + 9 bytes
_free_dbg(void * 0x0093a830, int 1) line 970 + 13 bytes
operator delete(void * 0x0093a830) line 49 + 16 bytes

Is there a problem running Xerces within a DLL? Is there a problem with a
buffer being allocated in some "other" context but being deleted in mine?

Thanks,
Jim Pearson
