[New-bugs-announce] [issue10182] match_start truncates large values

New submission from Martin v. Löwis <martin at v.loewis.de>:

_sre.c:match_start currently uses Py_BuildValue("i") to return the start index, which itself is of type Py_ssize_t. This will get truncated on x64 Windows if the start is > 2**31. PyInt_FromSsize_t should be used instead. Other usages of Py_BuildValue should be reviewed as well.
