After only.  I know the results of the GCC testsuite on SPARC/Solaris by 
heart, there was not a single regression.

Yes, definitely.  You were a bit perverse when you asked me to do this 
testing ;-)

As I have said since the very beginning, a version prior to 3.3.3 that 
doesn't exhibit the bug, on whatever platform you want.  I guess that, given 
how buried in reorg.c the bug appears to be, that's next to impossible.

Anyway, you don't need to convince me, only the branch maintainer.
