FWIW, I finally took some time to look at this properly, and it turns
out it is a gcc bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D70528
The fix, https://gcc.gnu.org/viewcvs/gcc?view=3Drevision&revision=3D235002=
,
has not been merged to the gcc 5.x branch, even though it seems fairly
trivial. We might want to apply this one manually to our gcc 5 ports,
for the mean time, while prodding upstream to merge it.
