At this stage we need to resort to gdb. Run the version of the program
compiled with -debug under gdb, and take a look at the backtrace when it
crashes. Hopefully it'll be somewhere in the RTS, if it's somewhere in
Haskell code you won't get an informative backtrace.
If it's possible for us to reproduce the bug here, I'll happily take a
look.
Cheers,
Simon
