[Haskell-cafe] New runtime crash, not sure what to make of it

[Joel Reymont]

Program compiled with -threaded on Mac OSX. Crash happens when  
waiting in select, I think.

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000
[Switching to process 832 thread 0x2303]
0x0011ce20 in stg_enter_info ()
(gdb) where
