Hello Ron, thank you, but it was not the run-time stack size I meant. It was the stack size for nested types which defaults to 20 or so IIRC. My nested types currently go to about 23 deep. Günther Am 04.02.10 14:46, schrieb Ron de Bruijn:

Hi,

I'm using deeply nested types in my app and exceed some stack-size in ghci.

I can't remember the runtime option I have to pass to ghci anymore, it's been about a year since I last pursued this approach. ghci +RTS --help suggests -K<size> Sets the maximum stack size (default 8M) Egs: -K32k -K512k. ghci is just another Haskell program which uses the GHC RTS.

Is it also possible to set this stack-size via pragma in the source code? Via an OPTIONS_GHC pragma, if possible.

Hello Serguey, great, that's the one! Can I set this in the source code itself too? Günther Am 04.02.10 15:26, schrieb Serguey Zefirov:

http://www.haskell.org/ghc/docs/latest/html/users_guide/flag-reference.html says that this option is dynamic so afaik it should work -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
