This is most likely PR10463.  I doubt it is a regression, it's
a bit hard to verify.  Apparently, ssa-ccp appeared for the first
time in GCC 3.1 (?), and I don't have such old compilers around.
The code with this bug is 4 (!) years old and very obviously wrong,
I guess that tells you something about how often this feature was
ever used  :-)
