Profiling doesn't work with SMP execution
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
