--- Comment #2 from Frank Ch. Eigler <fche@xxxxxxxxxx> ---
A few things jump out in that backtrace collection.
- pmNotifyErr() does PM_LOCK* work for no obvious reason. The syslog(3)
facility doesn't need it. The "stderr equivalent" block doesn't manipulate
shared data, except perhaps the pmprintf* stuff. Except pmprintf* uses locks
internally, and at the pmNotifyErr level isn't properly protected anyway, since
a PM_UNLOCK is placed too early.
- The actual crash appears to occur during a callq instruction, as it's writing
the return-pc into the stack. I don't have a theory as to why that should be
bad; the stack pointer etc. look ok. Continuing investigation.
