It seems that you are looking for something like Hat, which is a source level tracer for haskell, and possibly specifically for hat-stack, which is the stack tracer component.

You can alternatively use the debugger/tracer built into ghci. Not as nice as hat, but doesn't require to recompile your code and it's readily available. In case you wonder, it's the :trace command in ghci.

@mb14 Yes, in the past. However version 2.8.0.0 seems have problems to build cleanly on Windows due to an "unknown type name 'uint32_t" error message, in case this is the problem that you are seeing with it.
