Description

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
