Due to a "rogue $PATH" the failing gcc-4.7.0 in the report was built with a
non-standard gcc. To rule out that as a possible contributing factor, I have
confirmed (below) that when built with this system's /usr/bin/gcc the problem
remains.
$ /usr/local/bin/gcc -O3 -v -c testcase.c -save-temps
Using built-in specs.
