Here is a similar problem:

See Modules/mmapmodule.c .

Here a cast to ssize_t would, technically speaking, not be safe
either, but it may be worth using ssize_t anyways.

It should call PyInt_FromSize_t, without any casting. That will make it a PyLong if it's bigger than a Py_ssize_t, too.

Is there a simple automated way to detect situations like this? Maybe
there is a win64 compiler that would generate a warning.

I doubt it. Explicit casts are meant to silence warnings (among other things.) Warning for all casts is bound to generate quite a lot of warnings.
