indicate success/failure of the analysis. Add negation to subtrahend
in case of subtraction. Fail if both operands contain constants.

Shouldn't the priority of this bug be increased considering that it produces
wrong code on valid input and the affected package (Speex) is included in most
Linux distributions (fortunately most of these don't enable -ftree-vectorize by
default I think)?

I couldn't reproduce the problem on x86. I ran it with valgrind
--leak-check=yes, is it correct?

Could be x86-64 only, I don't know. I don't have a plain x86 with gcc 4.1 to
test on.
