Hi! There are currently at least two unresolved tickets[1][2] in our bug tracker regarding PaX MPROTECT / W^X protection issues with regard to PCRE JIT. The problem is that PCRE JIT mmaps W|X pages[3], what is no longer allowed on several platforms, such as OpenBSD, FreeBSD and SELinux. It seems that there are workarounds (e.g. using paxctl to allow W|X mapping[1], or mounting with wxallowed[4]), but these appear to be very system specific.
My best idea to resolve the reports is to document this issue. Maybe somebody has a better idea?
