Kazu,
What about 3e598fe0b01f4692f50c377ac91010040227e7ce in ghc? This was a
calling convention bug that Geoffrey fixed.
It looks like it is almost certainly the culprit.

Hi,
Some changes in the last 8 days fixed segfault on 32bit x86 with -O2:
http://ghc.haskell.org/trac/ghc/ticket/7953
I read recent log messages but I cannot guess which commits fixed this bug. Does anyone guess?
P.S.
Thanks to this, now I started running Mighty with multicore IO manager on mew.org. I'm watching whether or not multicore IO manager works stably in the real world.
