[New-bugs-announce] [issue9613] Python considers pid longs under 64-bit Windows

New submission from Antoine Pitrou <pitrou at free.fr>:

Under 64-bit Windows, Python aliases PyLong_FromPid() to PyLong_FromLong() (and PyLong_AsPid() to PyLong_AsLong()), but a C "long" is 32-bit, while apparently the MSVCRT defines a pid to be intptr_t, that is 64-bit. A potential loss of data ensues.
