Description
Compiling a Hello World program with -threaded and -prof results in a binary that segfaults immediately. This is with GHC-6.5.20060831.
$ cat Test.hs module Main where main = putStrLn "Hello world" $ ../ghc-6.5.20060831/usr/bin/ghc -threaded -prof Test.hs -o test $ ./test Segmentation fault $ ghc-6.4.1 -threaded -prof Test.hs -o test $ ./test Hello world
