I have same problem with php 7.3 installed via homebrew on mojave (both with bottle package or
compiled from source).
If i use xdebug extension no page can be viewed (php-fpm kill the child process).
If use php from command line without xdebug php works but kill when I use pcre functions.
Also if I use psysh (REPL cli) php crash on every command.
In all cases the code "crashed on child side of fork pre-exec" on php_pcre2_jit_compile or
php_pcre2_jit_match.
This is a crash report:

@nikic Indeed, you're right. This is not about the JIT stack,
but rather about the machine stack. From the docs[1]:
| There is a limit to the size of pattern that JIT supports,
| imposed by the size of machine stack that it uses.
I found an SO question which may be related[2], in which case this
wouldn't be Wordpress specific.

@cmb: Wouldn't that generate a JIT_STACKLIMIT rather than NOMEMORY error?

This warning is trigged, because pcre2_jit_compile() returns
PCRE2_ERROR_NOMEMORY, which hints at a too small JIT stack.

I am not able to reproduce the issue by singling out any specific preg_* function and parameters.
The ony way I can reproduce the issue is with a clean install of WordPress 5.0.
