Do you link with same same CRT as Python? (msvcr90.dll)
You should always use -lmsvcr90.
If you don't, you will link with msvcrt.dll.

For example, PyErr_SetFromErrno will return garbage if CRTs are shared.

Originally there was only one system-wide CRT on Windows (msvcrt.dll),

Well,
If F1 is run in Python shell, everything is properly working, BUT if call
