   I have used an older binutils version: 2.9.1. You are right, that 2.13.1
   doesn't complain BUT that doesn't mean thats better... GAS simply emits
   zeros where the older gas complained. I would like to see compatibilty
   with older versions.

   The bug is still present in the second 3.3 prerelease: "3.3 20030509
   (prerelease)". You should look at the generated code with "-O" and with
   "-O -fgcse". GCC shouldn't emit references to (local) symbols that aren't
   present in the first place. I call that broken.

 Hello,
 
 with binutils 2.13.1 and gcc 3.3 branch and mainline cvs (20030508), I  
 cannot repeat the bug you reported, ie no complaints from the  
 assembler. Can you verify whether you still encounter this bug in  
 current gcc 3.3 branch? Thanks,
 
 Dara
