> cachekey's Pattern class is not thread safe; it uses member data to store the result of pcre_exec(), but only one instance is shared between all threads.  This causes crashes when two threads access the pcre result at the same time.
> Fix: use automatic storage for the pcre result data.
> PR incoming.
