Comment 9 for bug 771903

This test case stopped failing, sort of, for 4.6 by r162943, the introduction of tree-bit-ccp optimization. However that revision merely masked the problem by default, as compiling with 4.6.[01] and -fno-tree-bit-ccp makes it reappear. The bug was finally fixed for 4.7 by r176911, the fix for the similar PR49799. That fix was also applied for 4.6.2 in r176917.

Backporting r176917 to 4.5 and 4.4 fixes both PRs there too.
