external program crashes when run through subprocess.popen on XP

[ckkart]

Hi,

on XP when starting a certain external program (plain C calculation
program which communicates via stdout/fs) from python 2.5 using
subprocess.Popen the external program crashes. It does not if started
directly from the XP command prompt. This is not a purely python
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.

Any ideas?

Thanks, Christian
