Description:
innodb_gis.rtree_purge fails with an assert:
2016-02-07 07:42:34 0x7f0334bf8700 InnoDB: Assertion failure in thread 139651746596608 in file rem0cmp.cc line 1162
InnoDB: Failing assertion: !(rec_get_info_bits(rec2, comp) & 0x10UL)
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.8/en/forcing-innodb-recovery.html

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.
key_buffer_size=1048576
read_buffer_size=131072
max_used_connections=1
max_threads=151
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 61014 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...

How to repeat:
Seen several times in last week's weekly.
I know that a number of bugs have been fixed or closed as dups in this area recently, but this one still shows up.
