[Msys2-users] Debugging undeterministic segfaults

[Gintautas Miliauskas]

I'm working on ghc trunk.

You were indeed right, the compiler was probably optimizing out my code.
The suggested crasher code works, and qtcreator gets invoked, although I
did not manage to set up gdb yet.

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.
