Show stack traces
Debugging stack overflows can be very difficult, because GHC gives very little information as to exactly what is overflowing. Showing a basic stack dump (on crash, or in the ghci debugger) would be enormously helpful.
(Entered after spending two days trying to determine the cause of a stack overflow, before discovering it was a GHC bug [3677], which would have been apparent immediately if I could have only seen a callstack.)
