https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243746 Conrad Meyer <cem@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Version|12.1-RELEASE |CURRENT CC| |cem@freebsd.org --- Comment #1 from Conrad Meyer <cem@freebsd.org> --- Yeah, our libunwind doesn't know how to backtrace out of a signal handler at this time. I have a WIP patch to unwind starting from a `ucontext`, which signal handlers created with sigaction(2) can access, but I haven't had time to work on it for a while; it would also require slightly different code in the signal handler. -- You are receiving this mail because: You are the assignee for the bug.help
