Re: 7.8.1 plan

Actually, the 0x200000 for the reserve was just the default in the executable - I just set it out based on what peflags told me initially. Thank you again Kyrill! On Thu, Apr 3, 2014 at 9:32 AM, kyra wrote:

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
