Please see
   http://gcc.gnu.org/bugs.html
for info on how to report bugs.  This bug report is lacking so much info 
that it does not appear to be of any use.

You failed to mention the target.  You mentioned %ebx in which we can 
imply that the target is x86, but it could also be x86_64.  You failed 
to mention the gcc version.  gcc 3.x.x isn't specific enough.  I 
seriously doubt that you have tried every gcc version.  Also, you failed 
to mention the exact options you are using, and the OS you are using.

I tried to reproduce this on the AMD64 SuSE 9.1 system on my desk.  The 
installed compiler is gcc-3.3.3 (SuSE Linux).  It works with -O, -O 
-fomit-frame-pointer, -m32 -O, and -m32 -O -fomit-frame-pointer.  I 
tried it with the gcc-3.4.x branch on the same platform with the same 
options, and it worked for all of them.

I tried this on an x86 system using RHL 9, where the system compiler is 
3.2.2 20030222 (Red Hat Linux 3.2.2-5).  It works with both -O and -O 
-fomit-frame-pointer.
