Summary: _subprocess.c calls PyInt_AsLong without error checking
Initial Comment:
_subprocess.c calls PyInt_AsLong without checking
whether the conversion produced an error.
This bug can cause an error to be reported at the wrong
point, eg:
Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310
32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for
more information.
>>> import subprocess
>>> si = subprocess.STARTUPINFO()
>>> si.wShowWindow = 2**65
>>> obj = subprocess.Popen('notepad.exe', startupinfo=si)
>>> 1+1
OverflowError: long int too large to convert to int
>>>

This code (for startupinfo) is only valid on Windows. The
problem seems to be at lines 379 and 380 in
PC/_subprocess.c. I'll let someone who can test this one
take care of it. The return result from getint() needs to
be checked.
