Phil Sorber commented on TS-4650:
---------------------------------
I know I am late to the show, be we should have converted this to Regex class.
I'll merge the back port as is, but maybe [~ftarnell] is interested in doing
the Regex conversion work in another issue?

> 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.
