Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to fail| |4.1.0, 5.3.0, 6.2.0, 7.0 --- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> --- The test case doesn't fail with -O2 prior to r193157 but it does fail with -O3 all the way back to r104500 so it doesn't appear to be a recent regression.
