On Windows, a Debug build doesn't inline Py_INCREF/DECREF even if it uses __forceinline. I looked at the Py_IncRef() and Py_DecRef() assembly in Visual Studio using a breakpoint.

Using /Ob1, Py_INCREF/DECREF are inlined as expected. I set this option in the pythoncore project.

Do you think that I should modify the 38 other projects of the pcbuild solution to enable /Ob1 in debug build?
