PyInt_FromLong gives segfault on small numbers (<257)

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

Re: Why is python not written in C++ ?

C++ is actually not that bad. Can't compare it to C, but nothing compares to C... I think the bad reputation it got (and still has) is from Microsoft's visual studio IDE (that was and still is horrible) A lot of good applications are written in C++, but many bad ones as well. Sorry for swearing in
