New description:
{{{
initializeWorld = (\w -> do
worldSetGravity w 0 (-1.0) 0
worldSetERP w 0.2
worldSetCFM w 1e-5
worldSetContactMaxCorrectingVel w 0.9
worldSetContactSurfaceLayer w 0.001
worldSetAutoDisableFlag w 1),
}}}
these worldSet* functions are unsafe FFI calls. initializeWorld is `Ptr
Int -> IO ()`
commenting this prevents this bug. this code is found in a top level
declaration:
{{{
initiailLevel = Level {
...
}
}}}
of which contains the record for initializeWorld
Comment (by simonpj):
You need to give us a few more clues! For example, the error message you
get.
But for this one we'll probably need to be able to reproduce your problem.
Can you make a small program that demonstrates it? Thanks
Simon
