Same program now prints this with `-O`: {{{ *** Exception (reporting due to +RTS -xc): (THUNK_2_0), stack trace: Main.f, called from Main.main, called from Main.CAF --> evaluated by: Main.main, called from Main.CAF --> evaluated by: Main.main Main: test CallStack (from HasCallStack): error, called at Main.hs:2:5 in main:Main CallStack (from -prof): Main.f (Main.hs:2:1-16) Main.main (Main.hs:4:1-19) Main.CAF (<entire-module>) }}} and this without `-O`: {{{ *** Exception (reporting due to +RTS -xc): (THUNK_2_0), stack trace: Main.f, called from Main.CAF --> evaluated by: Main.main, called from Main.CAF Main: test CallStack (from HasCallStack): error, called at Main.hs:2:5 in main:Main CallStack (from -prof): Main.f (Main.hs:2:1-16) Main.CAF (<entire-module>) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9525#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
