Unrelated question: this kind of code is quite common in connection with
user-defined arithmetic classes.  While I understand that changing the bug
priority from "P3 normal" will likely do nothing with regard to which releases
of gcc the fix will appear in, it might make a difference for distributors that
tend to cherry-pick important fixes ahead of regular releases.  For example,
the next release of Fedora is slated to be delivered using gcc 4.7.0, and its
miscompilation of LilyPond, a bonafide application, was what triggered this
report.

Given that the triggering pattern is quite typical for C++ and the problem
being present on all architectures, it might make sense to adjust the priority.
