GHC.ExecutionStack
This is a module for efficient stack traces. This stack trace implementation is considered low overhead. Basic usage looks like this:
import GHC.ExecutionStack
myFunction :: IO ()
myFunction = do
putStrLn =<< showStackTrace
Your GHC must have been built with libdw support for this to work.
user@host:~$ ghc --info | grep libdw
,("RTS expects libdw",YES)
