Summary: ghc fails with -O flags on Mandrake

Initial Comment:
Hi the Glorious GHC Team,  
  
I suppose that it can be considered a bug that ghc fails to  
compile with -On, n>0 option while it compiles fine with no 
optimisation flags. For example, for a module as simple as:  
  
  module Test where  
  f x = x  
  
compiler fails with:  
  
  [rysiek@home LHS]$ ghc -O -c Test.hs  
  Prologue junk?: .globl __stginit_Test  
  __stginit_Test:  
          pushl   %ebp  
          movl    %esp, %ebp  
  
Compilation goes through when it is called with ghc -c Test.hs.  
  
I installed ghc version 5.04.3 on my Mandrake 9.0 Linux from   
a binary tar.bz file. The installation process went problemless;  
below please find log files generated for ./configure and for  
make install.  
  
I wonder if the problem has anything to do with version  
differences   
between the libraries used to produce a binary distribution  
and the ones that came with Mandrake 9.0. Of course, I've got  
both libreadline.so.4 and libncurses.so.5, as specified  
on ghc download page. Still, I wasn't able to install ghc from rpms   
because of unsatisfied requirements. For example,   
  
(.....  
Andrew Moran's rpm complains:  
  
  [root@home rysiek]# rpm --install ghc-5.04.3-1.i386.rpm  
  error: failed dependencies:  
          libc.so.6(GLIBC_2.3)   is needed by ghc-5.04.3-1  
          libreadline.so.4   is needed by ghc-5.04.3-1  
  
I understand the first of these complaints: /lib/libc.so.6 comes  
from glibc-2.2.5-16mdk on Mandrake, so GLIBC versions differ.  
Still, I don't know, how to read the second complain  
  
  [root@home rysiek]# locate libreadline  
  /lib/libreadline.so.4  
  /lib/libreadline.so.4.1  
  /lib/libreadline.so.4.2  
  /lib/libreadline.so.4.3  
  
This means that libreadline.so.4 is available, so perhaps the name  
of  
its rpm matters:  
  
  [root@home rysiek]# rpm -q -f /lib/libreadline.so.4  
  readline-4.3-4mdk  
.....)  
  
Anyway, after installation from a binary distribution went  
problemless  I would expect compiler to work 99,99999% 
problemless. In a situation when -On, n>0 options don't work  
I am unable to install fptools from their original bunch, for 
example. I am also not sure if it was possible to compile ghc  
from its sources. (I didn't try it, I expect,  however, that ghc  
itself is best compiled with lots of optimisation flags.)  
  
With Best Regards,  
Rysiek

Please do the following, using the Test.hs you mentioned in 
the report:

$ ghc -keep-raw-s-file -c -O Test.hs

and attach the resulting file Test.raw_s.
