index_merge + partitioning + MyRocks crashes the server

14:10:47 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 https://bugs.percona.com/key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=1
max_threads=151
thread_count=2
connection_count=1
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 67949 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.Thread pointer: 0x7fb2ed417000
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...
