Regexp_processor_pcre::fix_owner() called Regexp_processor_pcre::compile(), which could fail on the regex syntax error in the pattern and put an error into the diagnostics area. However, the callers: - Item_func_regex::fix_length_and_dec() - Item_func_regexp_instr::fix_length_and_dec() still returned "false" in such cases, which made the code crash later inside Diagnostics_area::set_ok_status(). Fix: - Change the return type of fix_onwer() from "void" to "bool" and return "true" whenever an error is put to the DA (e.g. on the syntax error in the pattern). - Fixing fix_length_and_dec() of the mentioned Item_func_xxx classes to return "true" if fix_onwer() returned "true".
