Problem: SELECT ... REGEXP BINARY NULL may lead to server crash/hang. Fix: properly handle NULL regular expressions. mysql-test/r/func_regexp.result: Fix for bug #39021: SELECT REGEXP BINARY NULL never returns - test result. mysql-test/t/func_regexp.test: Fix for bug #39021: SELECT REGEXP BINARY NULL never returns - test case. sql/item_cmpfunc.cc: Fix for bug #39021: SELECT REGEXP BINARY NULL never returns - checking regular expressions' null_value we tested it without a val_xxx() call before, which is wrong. Now Item_func_regex::regcomp() returns -1 in the case and allows to handle NULL expessions properly. sql/item_cmpfunc.h: Fix for bug #39021: SELECT REGEXP BINARY NULL never returns - checking regular expressions' null_value we tested it without a val_xxx() call before, which is wrong. Now Item_func_regex::regcomp() returns -1 in the case and allows to handle NULL expessions properly.
