Re: Segfault on x86 with -O2

Lesson learned (for me at least): add regression tests to the testsuite when reporting compiler failures.

And just for the record, people reported this morning they couldn't reproduce #8103 anymore, and I'd bet this probably fixes that one, too.

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.
