Problems embedding with win2k

I need to embed a python interpreter in C++ applications in both Win2K
and Linux environments. I have started to work the embedding examples
and have run into problems on the windows side, here is my setup and
problem:
Environment:
Win2K Pro, VC6 SP4
Problem 1Very High Level Embedding Example: Access violation in
msvcrtd in debug mode
I work the first example from the Python docsextending and embedding
sec 5.1. When I build this in release mode the application runs fine.
When I compile and run in Debug mode I get an access violation in
msvcrtd.dll. When the program is run the following two asserts fail:
Dbgheap.c line: 1044
_CrtIsValidHeadPointer(pUserData)
Dbgheap.c line: 1050
_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)
When I look back through the trace, this error occurs when in
Py_Initialize() when the site module is being imported. I am using
the debug multithreaded dll runtime for debug and the multithreaded
dll runtime for release. I am sure I must have a project setting
wrong but I can't figure out exactly what.
Problem 2Pure Embedding ExampleAccess violation in python22.dll
When the pure embedding example is built in release mode using the
multithreaded dll runtime, I get and access violation. When I try to
build and run in debug mode I get the same problem in Py_Initialize()
as described in Problem 1.
If anyone has seen this problem and can suggest a way forward I would
be very grateful.
