I have developed various profiling and debugging tools in the past, but haven't done any work in that direction for GHC compiled Haskell programs. I thought a good start might be to write a document detailing how the call stack works in GHC, and also write a basic debugger stack trace tool. Here:


I hope this is helpful to people trying to pin down crashes, and people interested in working on debugging / profiling tools. I'd also really appreciate if somebody with more GHC / RTS knowledge than me would have a look and see if I got things right.
