[New-bugs-announce] [issue3977] Check PyInt_AsSsize_t/PyLong_AsSsize_t error

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

PyLong_Ssize_t() returns -1 and set an error (OverflowError) on
overflow, but some modules don't check this case. Here is a first patch
for BytesIO() and StringIO().
