[issue16736] select.poll() converts long to int without checking for overflow

2012-12-20 Thread Richard Oudkerk 

New submission from Richard Oudkerk:

Relevant code:

int timeout = 0, poll_result, i, j;
...
tout = PyNumber_Long(tout);
if (!tout)
return NULL;
timeout = PyLong_AsLong(tout);  <-- implicit cast to int
