Thanks for having a look at this. The sourcecode is available from http://www.doc.ic.ac.uk/~jak97/graphics.tgz Please let me know if you have any difficulties building. SDL is available from http://www.libsdl.org and SDL_image is available from http://www.devolution.com/~slouken/SDL/projects/SDL_image/ Cheers John On Monday 28 May 2001 10:07 am, you wrote:
The error means that GHC's garbage collector has come across something it doesn't understand.
It's either a bug in the GHC garbage collector, or in GHCi itself (which plays fast and loose with types in one or two places) or in something to do with the SDL graphics interface.
Bugs like this are really hard to find, unless we can reproduce them here. Can you send us all the code?
