I've tried to search for "basic_string race" with all statuses:
https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=SUSPENDED&bug_status=WAITING&bug_status=REOPENED&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&cf_known_to_fail_type=allwords&cf_known_to_work_type=allwords&component=libstdc%2B%2B&list_id=125385&query_format=advanced&short_desc=basic_string%20race&short_desc_type=allwordssubstr
But it does not yield anything interesting. What bugs can I reference?
