Latest mpv on snapshots on my X250 dumps core whenever I quit playing with `q' or `Q'; I have no mpv config and this happens regardless of any values for the vm.malloc_conf and hw.smt sysctls:

(Quit) pthread_mutex_destroy on mutex with waiters! Segmentation fault (core dumped) The pthread_mutex_destroy line has always been there but dumping core is new behaviour, it most certainly started after upgrading to a newer snapshot around one or two weeks ago and/or moving my installation/SSD from an X230 to an X250 thinkpad (same config, just hardware swap). $ egdb --quiet -se `which mpv` -c ./mpv.core -batch -ex bt -ex l [New process 256621] [New process 165240] [New process 528996] [New process 170944] Core was generated by `mpv'.
