---------------------------+------------------------------------------------
I get the following runtime error in my application on my 4-core i7
macbook pro, running GHC 7.4.1 and the llvm backend. I only get this error
if I specify -N greater than 4 (perhaps this is a hyperthreading related
problem?) and only when the application itself calls the function 'error'.
This happens whether I compile with -fllvm or not. My application is
called 'mrfy':
mrfy: internal error: mrfy: internal error: scavenge_stack: weird
