https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219228 --- Comment #1 from Duane <parakleta@darkreality.org> --- I rummaged a bit more in the code, and I might be on the wrong track, but it looks like `reschedule_signals()` is called whenever the mask is changed (s= uch as when a handler is launched) and if the signal is still pending and in the `block` set then `sigtd()` is picks an arbitrary thread if they are all blocked, and then since the process wants to catch the signal (i.e. `SIGISMEMBER(ps->ps_sigcatch, sig)` this calls `tdsigwakeup()` to force a wakeup of the thread even if it is blocked from receiving the signal. I think either `sigtd()` should default to the main thread rather than the = most recent, or else the `SIGISMEMBER` test should also check `!SIGISMEMBER(td->td_sigmask, sig)` before calling `tdsigwakeup()`. Or may= be both of these changes. --=20 You are receiving this mail because: You are the assignee for the bug.=
