Bug Description
While running mysql-debug --debug --user=mysql and shutting down server, I noticed
mysqld-debug: debugger aborting because missing DBUG_RETURN or DBUG_VOID_RETURN macro in function "?func"
11:59:18 UTC - mysqld got signal 6 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Please help us make Percona Server better by reporting any
bugs at http://
key_buffer_size=0
read_buffer_
max_used_
max_threads=10000
thread_count=2
connection_count=2
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

in the manual which will help you identify the cause of the crash.
=======
I presume this is because DBUG_RETURN is missing in start_wsrep_THD (or one of its callees)
