Hi, how does mingw build extensions modules play with an official cpython interpreter ? If you build such a module with a ms compiler which has a different version as the one python was build with, your module will crash.
I suppose the problem comes from different runtime dlls as msvcrXX.dll, but how does mingw handle this ? Regards, Uwe.
