This seems very strange indeed - I immediately suspect something odd 
with your hardware.  Try swapping out RAM, if you can.

Strange that it only seems to affect Perl (Perl is running the mangler 
that generates that .s file).  I suppose it's possible there could be 
something strange with your Perl - maybe try replacing that?

If you run GHC with -keep-tmp-files, you can capture the erroneous .s 
file for later inspection; that might give us more clues.
