Could you expand on this fragment of code? Perhaps a fullying
compilable example? It depends how you are getting the pointer, not
how you are reading data out of the pointer. For example, if you use
"withCString" to get ptr then the memory will be freed automatically.

Hello, I get a segfault when I do str <- peekCString ptr free ptr return (Just str)
But not when I don't free the C pointer. I also get the same behaviour with ByteString.packCString...
Could you please tell me if the memory is correctly freed by GHC when I don't do it myself? And how can I specify a custom free function (i.e. xmlFree function in libxml2)? Maybe I should use a data type with two fields : the String/ByteString and the ForeignPtr to the CString?
