Re: 7.8.1 plan

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! On Thu, Apr 3, 2014 at 8:50 AM, Austin Seipp wrote:

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
