4532	Profiling crashes with GHC API	guest		"Profiling program using ghc api crashes.

For example:

ghc-api.hs
{{{
import GHC
import GHC.Paths

main = do
  runGhc (Just libdir) $ do
    getSessionDynFlags >>= setSessionDynFlags
    dynCompileExpr ""()""
}}}

Compile ghc-api.hs with following options:

{{{
$ ghc --make -prof ghc-api.hs
}}}

Run ./ghc-api with ""+RTS -p"" flag on, then program crashes.

{{{
$ ./ghc-api +RTS -p          
ghc-api: internal error: PAP object entered!
    (GHC version 6.12.3 for i386_apple_darwin)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
zsh: abort      ./ghc-api +RTS -p
}}}
