--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
I can reproduce the warning with GCC 8 but not 9.  GCC 10 doesn't compile t=
he
code anymore so I can't test it there.  GCC 8 takes 70 seconds to churn thr=
ough
all the code so that's seems too long to reduce it to a small enough test c=
ase
for an outdated compiler/concepts implementation.  Given that -Wuninitializ=
ed
has lot of known problems, both with and without sanitizers, I'm going to
resolve this as WORKSFORSOME.=
