在vc下使用msxml的时候遇到_CrtIsValidHeapPointer(pUserData)

搜索到以下东西

 

When I execute my program (it's multithread and has COM and dll),
there is an error message as follows:

Program D:/dongle_1/TestAP/bin/Debug/TestAP.exe
File: dbgheap.c
Line: 1132
Expression: _CrtIsValidHeapPointer(pUserData)
For information on how your program can cause an assertion failure, see
the Visual C++ documentation on asserts.
========================================
==========
I read the dbgheap.c and find the line 1132, it's as follows:
/*
* If this ASSERT fails, a bad pointer has been passed in. It
may be
* totally bogus, or it may have been allocated from another
heap.
* The pointer MUST come from the 'local' heap.
*/
1132: _ASSERTE(_CrtIsValidHeapPointer(pUserDat
a));


========================================
=====================I also use
google to find some answers.
They said
(1) If you are developing multithread application, be sure to link it
with
the correct runtime library(/MD, /MT). That what
"The pointer MUST come from the 'local' heap." means.
Check what "ruintime library" you use. It should be "Multi threaded (
debug ) DLL"

(2)
Not only must they match, they must both be DLL versions. If they're
static versions, each piece (the exe and the dll) will have their own
heap and the OP will still be deleting from mismatched heaps.
I'd also be suspicious of general design issues given the way the OP's
main program is having to clean up for the dll.

You'll get this problem if you use two different run-time libraries,
one to
allocate the memory and one to de-allocate the memory. Open up the
project
settings dialog, switch to C/C++ tab, set Category to Code Generation
and
check the Use run-time library combo box. These must match in any
modules
that share the task of allocating and destroying memory.
