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)
Since: base-4.9.0.0
