on XP when starting a certain external program (plain C calculation

problems since the crash occurs as well if started e.g. from a msys
bash shell. The only things I find worth mentioning from the windows
debugging message is that FileVer and ProdVer of msvrct.dll differ, I
am no windows expert though.
I just obseerved that the program does not crash if called via
subprocess.call
so it seems to be related with having a way to communicate with the
external
program or not.
Maybe the program attempts to write something to stdout/stderr? If you use
Popen(..., stdout=None, stderr=None, ...) then the subprocess' standard
handles will be invalid, and it will fail as soon as it attempts to write
something.
