Bug Description
After this command issued on one cluster node:
alter user user() identified by 'new-pass';
all the other nodes crash with stack trace as below.
But command:
alter user 'root'@'localhost' identified by 'new-pass';
does not make any problems though. Tested on PXC 5.7.17
14:44:59 UTC - mysqld got signal 11 ;
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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
Please help us make Percona XtraDB Cluster better by reporting any
bugs at https:/
key_buffer_
read_buffer_
max_used_
max_threads=210
thread_count=5
connection_count=0
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.

This is due to involvement of the function that is local to the node.
Here is the bug logged upstream with test-case.
