A strange bug indeed, but what brings you to this conclusion? As far as I
can tell, the program exits mysteriously when run normally, but runs when
invoked with +RTS -s. It also appears to run properly under gdb. I have no
idea what could cause this; we need to know more about what is making the
program exit prematurely. It's unlikely that the program is overflowing the
reserved area of the C stack - it would need to spill 512 words (or more?
Julian increased this recently for the NCG I think).
Julian is currently making an NT build, so we'll be able to take a look at
it when that's ready.
Cheers,
Simon
