Seems to me a some CAS problem. Unfortunately, I'm not familiar with arm architecture. Test, adopted to the FreeBSD here: https://people.freebsd.org/~dchagin/tst-cond25.c Btw, I tested it under qemu on mac os m1, maybe problem is here? --=20 You are receiving this mail because: You are the assignee for the bug.=
