Bug#24400628: DEBUG ASSETION KICKS IN WHEN LONG SUBPARTITION NAME

Browse Source 
IS USED IN CREATE TABLE

The problem was that using a very long subpartition name could
lead to the server exiting abnormally.

This patch fixes the problem by reporting ER_TOO_LONG_IDENT
if a name with more than 64 characters are used as partition
and subpartition name.
