PyInt_FromLong gives segfault on small numbers (<257)

[Marcos Prieto]

Hi,

I'm trying to call python (python 2.6) functions from C++ using MS VC+
+ 6.0 and any calls to PyInt_FromLong with numbers below 257 give me
exceptions, no problems with bigger numbers

PyObject *pValue;

pValue = PyInt_FromLong(1L); (or pValue = PyInt_FromLong(1);


Any ideas of what can I be doing wrong?

Thanks,

Marcos.

Have you called Py_Initialize() before?
