Description (last modified by simonmar) (diff)

This happened to me this morning; 

n142233:thesparse arthurvl$ ghci +RTS -H1024M -k128M -RTS
Segmentation fault
n142233:thesparse arthurvl$ ghci +RTS -H1024M -k8M -RTS
Bus error

Obviously this is a typo, but the response is somewhat unexpected. And yes, the heap-hint is needed, as without the heap hint it turns into: 

n142233:thesparse arthurvl$ ghci +RTS -k8M -RTS
Too late for parseStaticFlags: call it before newSession
n142233:thesparse arthurvl$ ghci +RTS -k128M -RTS
Too late for parseStaticFlags: call it before newSession
