The special case with NULL as a regular expression was handled at prepare time. But in this special case the item was not marked as fixed. This caused an assertion at execution time. Fixed my marking the item as fixed even when known to return NULL at prepare time. mysql-test/r/func_regexp.result: Bug #31440: test case mysql-test/t/func_regexp.test: Bug #31440: test case sql/item_cmpfunc.cc: Bug #31440: mark the item as fixed even when known to return NULL.
