--- Comment #34 from Alex Tutubalin <l...@libraw.com> --- (In reply to Kyle Evans from comment #33) tried: dtrace -n 'fbt:::return /(int)arg1 == EPERM && pid == $pid/ { stack(); }' -c '/usr/sbin/jail -c example' it says: dtrace: description 'fbt::return ' matched 36022 probes and provides 1.7MB output/ 48k lines. Probably this is not you're looking for. Sorry, I'm FreeBSD user, not developer, know nothing about dtrace, so I can run test command sequences in monkey mode, but I'm unable to modify your one-liner for better match. -- You are receiving this mail because: You are the assignee for the bug.
