David, In GHC-iPhone the number of function pointers that are allowed to be active for a given function is limited, but you can change the size of the limit. This is documented in http://projects.haskell.org/ghc-iphone/downloads/GHC-iPhone.pdf on p5 under 'Pool sizes for foreign function "wrapper" callbacks'. Steve On 18/06/11 11:29, David Pollak wrote:
Howdy,
I tried to build a function that would create an auto-freeing function pointer:
runOnMain :: IO () -> IO () runOnMain todo = do func <- funky dispatchFunc func where funky = mkStrCB $ \v -> do todo func <- funky freeHaskellFunPtr func
Unfortunately, I wind up getting: internal error: iPhoneCreateAdjustor - adjustor pool 'Main_d2K2' is empty (capacity 32) (GHC version 6.10.4-iphone-simulator for i386_apple_darwin)
I'm not sure why, but I suspect that funky is being called recursively and thus stuff is never being freed.
Any hints as to the issue and solutions?
Thanks,
David
