This happened to me this morning;
{{{
n142233:thesparse arthurvl$ ghci +RTS -H1024M -k128M -RTS

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
}}}
