I would like to nominate this patch for gcc-5.2 release. According to
downstream bugreport [1], gcc-5.1 is unusable for 64-bit wine:
"Breaks all of wine, no easy workaround -> blocker."
Due to severity of this bug, and importance of Wine, I'd like to
postpone the 5.2 release for a week, so this bug gets some testing in
the mainline, before it is backported to gcc-5 branch

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.
