$ python --version

Python 2.6.2

The core can be looked at with that "gbd python core" command. Thanks. It
shows the three warnings below and they are repeated numerous times, always
as warnings.

This GDB was configured as "i586-pc-interix3"...

Core was generated by `python /usr/local/bin/scons -H'.

My system is Interix 6.1 and 64 bit system. Microsoft regard Interix as
third-party software now. The Microsoft link about vfork you had is for
Interix 3 and written back in 2005. I hope it has been fixed?? In the
python makefile, it has

MACHDEP= interix6

The configuration may be the culprit.

I don't know anything about Interix -- does Microsoft even still support it?
If it's Unix-like enough, you can try to do

gdb python core

and then type 'where' to see the stack trace. But that will be at too low a
level to see what python was trying to do at the time of failure. And your
log above shows it might not even be writing the core files it says it is.

I suppose it could be this issue: http://support.microsoft.com/kb/328684
Might be worth trying that patch anyway.

Does python work at all?
