Confirmed broken on branch and mainline (20030707). However, reducing this is really 
unpleasant... Note that this bug belongs in the 'target' category, and only the flags -O2 -
mdisable-fpregs are necessary to reproduce this. If someone else would like to reduce this to a 
smaller testcase, that'd be great...

David Anglin already committed a patch for the mainline and is going to commit it for 3.3 branch 
after testing so assigning it to him.
