--- Comment #33 from Martin Sebor <msebor at gcc dot gnu.org> ---
With the workaround in r11-7146 the warning should no longer be issued for
std::string::insert.  Thanks to r12-2087 suppression by #pragma GCC diagnos=
tic
works reliably even with inlining in GCC 12, so the warning can also be
suppressed using it.  I'm not working on any other improvements related to =
the
underlying problem but I think this report can be resolved as fixed in GCC =
11
and 12.=
