Hm. I'd rather burn this with a RC2 released soon or defer it to
GCC 5.3. The patch looks kind-of straight-forward, likely not
affecting anything else (to my naiive eyes...).
So - please get it committed to the GCC 5 branch as soon as possible.
A GCC 5.2 RC2 will be done on Monday latest then (possibly during the
weekend if I find the time to do it).
Note this opens the window for other important wrong-code fixes - please
CC me on any you'd like to propose for GCC 5.2 and wait for my
explicit approval.
Thanks,
Richard.
