Does this help, really?  I've tried that occasionally, but can't really
say it's ever helped pinpoint the problem.  (Not complaining, stack
traces are hard in Haskell.)

I generally heap-profile (often with the -hd option), most stack
overflows will also retain heap data (i.e. a stack of (+) operations
will point to all the numbers as well), which should give you an idea of
where to look.
