--- Comment #7 from Iain Sandoe <iains at gcc dot gnu.org> ---
additional notes:

1. jamming -std=c++11 into stage2 and 3 cxxflags did not make any difference (I
was wondering if some c++17 copy elision thing might have changed the number of
temporaries).

2. still there at r15-644 (no surprise)

3. building the object using the stage3 compiler gives the same result as the
stage2 one.

4. building the object with the stage3 compiler and -fcompare-debug succeeds.

5. (although it's still out of tree) my aarch64-darwin branch, rebased onto
r15-644 also fails in the same way.

(not that any of these observations gets us any closer .. )=
