Sorry for dropping the ball on this again. I've applied the patch locally and I'm testing it now. Unless I'm mistaken, you do not have a copyright assignment on file with the FSF, is that right? Are you able to certify that you have the right to submit this to GCC, as described at https://gcc.gnu.org/dco.html ? Also, if GCC is failing to diagnose the invalid comparisons here then that should be reported to bugzilla as a c++ "accepts-invalid" bug.
