The assertion in String::copy was added in order to avoid valgrind errors when the destination was the same as the source. Eased restriction to allow for the case when str == NULL. mysql-test/r/func_set.result: Bug#45168: Test result mysql-test/t/func_set.test: Bug#45168: Test case sql/item_strfunc.cc: Bug#45168: Code cleanup and grammar correction in comment sql/sql_string.cc: Bug#45168: Fix
