EVACUATED object entered! (when doing FFI)

[Simon Peyton-Jones]

It's certainly a bug of some kind.  Please say what version of GHC you
are using.  If it's the latest one (5.04.1), please send us the source
code.

Thanks

Simon

| Good morning,
|=20
| I wrote a very small program, and it executed ok.
| I wanted to export a function in "C", and therefore wrote a "C"
wrapper
| function over it to invoke peekCString and peekArray on the input;
newCString
| and newArray on the output.
|=20
| I then did a small "C" driver program. Everything compiled and linked
| correctly.
|=20
| But at execution the program prints :
|=20
| EVACUATED object entered!
|=20
| as soon as "startupHaskell" is invoked (i.e. even before I call my
foreign
| exported function !)
|=20
| What is the meaning of this message ?
|=20
| Thank you
