Hello!
I was asked from https://bugs.php.net/bug.php?id=78630 to share my opinion.
Jit compilation did not work for me on pcre2 on php, as it turned out because I
had "/tmp" and "/var/tmp" mounted with the noexec flag, which makes it
impossible to use the JIT compiler.
But I believe that this is the correct setting, from a security point of view,
and for the jit-code you need to use the "/run" directory, because this is what
it was created for.
