Question

How can I stop Hint, a Haskell runtime interpreter library, from crashing the GHC interpreter?
It gives “Bus Error”, “Illegal Instruction” or “Segmentation Fault” when I try to load a module using it into the GHC interpreter. This a major problem and not just an annoyance because it also crashes my application when I use hint to load code that itself uses hint. I suspect this is related to the large amount of libraries Hint drags in when linking.

I am using Mac OS 10.6.8, GHC version 7.0.4

Answer 1

I solved this problem by explicitly passing the function to all code loaded.

For example, instead of doing

module Go where
import Run

go :: IO ()
go = do
  blah blah ....
  runFile etc ...

I did

module Go where

go :: RunFile -> IO ()
go runFile = do
  blah blah ....
  run runFile etc ...
