--- Comment #21 from Segher Boessenkool <segher at gcc dot gnu.org> ---
It will be fixed in the next releases of all still supported branches
(that's GCC 7, 8, and 9), and also in the upcoming GCC 10 release of
course.

If you are in a hurry, you can build your own compilers right now, the
problem has been fixed in all open release branches.

If, alternatively, you get your GCC from some distribution, ask them
about *their* release plans.  We don't know.

No future releases for GCC have been announced.  Judging from historical
trends the next (and last) GCC 7 release (7.5) will be in November, GCC 8
(8.4) in December, GCC 9 (9.3) in Februari, and GCC 10 (10.1) will be
there in May.  This is just *my* estimate, your mileage may vary, etc.
