Btw, it is committed size which is important here. I proposed to
increase both only to follow Linux/OSX linker policy which sets stack
size to be 8mb by default, otherwise we could stay at 1mb for both
reserved (windows' default value) and committed values.

Kyrill, you are fantastic! I confirmed this incantation seems to have
fixed the problem on my build:
$ peflags --stack-reserve=0x200000 --stack-commit=0x200000 ghc.exe
with the RC2 build, and not my own. Hooray!
I will work up something soon. Thanks so much again!

Oh excellent, thank you for the tip Kyrill, I had no idea about this!
My build is on the way, so I will try this and report back soon.

Right now, Kyrill has suggested a fix I'm attempting (I slightly
botched my first try), and I have found a way to avoid it at the
moment by turning off optimization (which seems to reduce stack
pressure enough to get by on Windows - see the ticket for details).
It's absolutely not necessary to rebuild everything to check if this works,
it's enough to edit ghc.exe with peflags utility (which has --stack-reserve
and --stack-commit options) and look if it stop segfaulting. If I could
reproduce the problem I'd have done this long ago.
Cheers,
Kyra
