I think I have an idea of what's going wrong here. hvr@ was right in
pointing out that we need to be careful with the PATH. It seems that
the bundled gcc is picking up the system-wide DLLs, and bad things
happen because of version incompatibilities. That does not explain
why "rm" is crashing, but maybe that's fallout from cross-process
damage. I will do some more testing. If this is indeed the cause,
then hopefully debugging will not be needed anyway.
Update: even after setting PATH to have the embedded gcc path in the
first position to make sure that the right DLLs are, I still got a few
segfaults, so this is probably not it.
Is it always GHC that segfaults, or one of the other programs it
invokes, like gcc?
Have you tried to reproduce this on another machine, to rule out
hardware problems?
Cheers,
Simon
