Bug#19904003 INNODB_LIMIT_OPTIMISTIC_INSERT_DEBUG=1 CAUSES INFINITE PAGE SPLIT
The debug configuration parameter innodb_optimistic_insert_debug
which was introduced for testing corner cases in B-tree handling
had a bug in it. The value 1 would trigger an infinite sequence
of page splits.
Fix: When the value 1 is specified, disable this debug feature.
