--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
Fixed for GCC 12, no older release branches are active anymore.
For the record, compiling with affected GCC but link editing against fixed
libstdc++ makes the testcase no longer terminate but at the expense of not
unlocking the mutex. So the failure mode changes from abort to (possible)
deadlock. Which possibly means "don't do that then" (link edit against
newer libstdc++).
