With the 8.43 release, if you jit compile a regex, then fork(), the child
will crash when trying to do a match or compiling a new regex. I compiled a
version where MAP_JIT was not set and things worked fine.
This is causing problems for my program (https://github.com/tstack/lnav)
I use child processes quite a bit. I noticed this after brew updated their
of pcre to 8.43.
