Hi! PHP7 supports PCRE's JIT compilation of patterns by default, which mostly works fine. However, there are issues when the matching exceeds the JIT stack limit, see bug #70110[1].
I'm not sure how to solve this best. Basically, I see two possible solutions: either we fall back to non JIT matching, if pcre_exec() fails with PCRE_ERROR_JIT_STACKLIMIT, or we use a custom JIT stack and make its size a configurable ini setting (similar to pcre.backtrack_limit), and raise E_WARNING if the matching fails due to limited stack size.
