[Haskell-cafe] how to debug stack overflow?

What is the recommended method
to find the exact reason for a stack overflow
(when running a Haskell program compiled with ghc)?
When I compile with -prof -auto-all, and run with +RTS -xc,
I see a very short call stack, which can't be right.
But that's probably because I am calling some library method
that was compiled without -auto-all so it's invisible in the trace?
I can avoid the overflow by +RTS -K1G or something
but I want to investigate because it might indicate
some inefficiency in the code (evaluations happening
at the wrong time).
