[Bug 253318] lldb: aborted when debugging named

--- Comment #3 from Xin LI <delphij at FreeBSD.org> ---
It would take about a day for me to catch the offending program (more context
at https://gitlab.isc.org/isc-projects/bind9/-/issues/2465 if you are
interested) to enter the state that I need to debug, so it would take some time
for me to try to reproduce the lldb issue.

What I did was fairly basic, basically I have a runaway BIND instance, which
after receiving a SIGTERM won't exit, and I was attaching to the process and
trying to get a backtrace for all threads.

Or in other words, I did:

sudo lldb --attach-pid `pgrep named` `which named`

and were going to do a "thread backtrace all", while doing that I might have
pressed <tab> and lldb dumped core.

===

Should I build a lldb version with -g and -O0 just in case, by the way?
