Problem when compiling with -prof -fasm

Hello,

when compiling anything with -prof -fasm, I get the following response:

ghc-6.0: panic! (the `impossible' happened, GHC version 6.0):
        AbsCStixGen.gencode
CC_DECLARE(CGI_CAFs_cc,"CAF","CGI",CC_IS_CAF,);

Please report it as a compiler bug to glasgow-haskell-bugs@xxxxxxxxxxx,
or http://sourceforge.net/projects/ghc/.

(without -fasm I get

Prologue junk?: .globl __stginit_CGI
        .type   __stginit_CGI,@function
__stginit_CGI:
        pushl   %ebp
        movl    %esp, %ebp

instead, which is probably caused by non-supported version of gas or gcc?)
