ghc-6.4 crashes on windows 2000

Today I installed ghc-6.4 (binary) on windows 2000.

I tried to compile my webserver. It consists of very
basic code and uses no fancy features (although I need
to give -fglasgow-exts for some empty data declarations
etc.). Under linux (mandrake 10.1), ghc 6.4 (also a
binary) compiles my webserver just fine.

Under windows, however, ghc crashes 90% of the runs,
giving various scary error messages, such as:

***
ghc.exe: internal error: scavenge:
unimplemented/strange closure type 44304 @ 01F6137C
***
ghc.exe - Application Error

The exception Illegal Instruction
An attempt was made to execute an illegal instruction.

After ~20 tries, the program finally compiled and seems
to run ok. The crashes seem to occur regardless of
optimisation flags.

Please contact me at ariep@xs4all.nl if you need to
know anything else.
