================== Testcase
SET @@GLOBAL.innodb_track_changed_pages=TRUE;
SET @@GLOBAL.innodb_track_redo_log_now=1;

Highly likely a dup of bug 1368530 but with a very different outcome on a minor difference in commands

SET @@GLOBAL.innodb_track_changed_pages=1;
SET @@GLOBAL.innodb_log_checkpoint_now=TRUE;

Idem crash.
