Bootstrap fails in libstdc++ with the following error.
I haven't investigated it much except to take a peek
at recent libstdc++ commits where r261525 looks like it
introduced __glibcxx_check_can_increment_range, so it
seems like it might have something to do with it. I don't
see a __glibcxx_requires_can_increment_range macro defined
anywhere in the patch so maybe it's a typo? Francois, can
you please see what's going on?

I had missed the fact that the patch didn't apply correctly on
include/debug/debug.h as stated in the ChangeLog entry.
It is fixed now.
But even after r261537 we are seeing the regressions:
FAIL: g++.dg/warn/pr31246.C -std=gnu++11 (test for excess errors)
FAIL: g++.dg/warn/pr31246.C -std=gnu++14 (test for excess errors)
FAIL: g++.dg/warn/pr31246.C -std=gnu++98 (test for excess errors)
Which definitely are related.
And failing Debug Mode tests:
FAIL: 20_util/hash/84998.cc (test for excess errors)
FAIL: 23_containers/vector/cons/destructible_debug_neg.cc (test for excess
errors)
FAIL: 25_algorithms/binary_search/partitioned.cc (test for excess errors)

FAIL: 25_algorithms/upper_bound/partitioned.cc (test for excess errors)
FAIL: ext/profile/mutex_extensions_neg.cc (test for excess errors)
The logs show:
