**Reported in Launchpad by Arman Jakupovic last update 01-12-2017 20:51:11

I'm sorry if I'm not providing enough information. I'm new to all this.
A couple of days ago we upgraded our mysql5.5 server to percona-server-5.7. We didn't really do an upgrade more like taking a dump of all databases and then deleting the old server, followed by install of percona server 5.7 and then import of big database file.
Today I was doing some tweaking and needed to query the information_schema. So I did a SELECT * FROM information_schema.tables and this caused the server to crash. I tried selecting the table columns aswell and this also crashes the server each and every time. This is the error message I got.

22:56:31 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 Server better by reporting any
bugs at http://bugs.percona.com/

key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=2
max_threads=526
thread_count=2
connection_count=2
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2241389 K bytes of memory
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...
