Taral, Thanks for the information. I have ran the apple hardware test and it reported that there were no errors with the RAM (although I'm not convinced there is nothing wrong with the RAM). Perhaps it could have been a problem with the ghc installation (i.e. a bit got flipped in the executable during build). Is it possible to uninstall ghc? Thanks. Chris.

Taral,
What is a bit-0 error? and how do I find out if I have bad RAM?

If you look at the ASCII values, you will find that the least significant bit (bit 0) of the corrupted character is set when it should not be. This is a bit-0 error, and usually indicates a problem with your RAM.
You will need to find a memory tester to find out if you have bad RAM. If you don't have a memory tester, you can switch out the RAM with known good RAM to see if the problem goes away. If you are not familiar with these things, you may want to enlist the aid of a professional.
