I'm running a CentOS 7 on a physical server, and I found a warning about JIT out of memory. The problem appears on a WordPress 4.9.8 installation when migrating to PHP 7.3RC2. PHP 7.3 update to the PCRE2 version of the library.
Log saves lots of warnings, in every preg_match and preg_replace, and it is always the same: JIT compilation failed. No more memory.
As far as I could debug the function results were correct.
If I try to debug a simple preg_match call on a small PHP file, the problem does not appear, but on another big PHP site like phpMyAdmin, it happens again.
I couldn't find anything on the web, and I think it is a very particular problem of either the implementation of the PCRE2 library in the Remi Repo or the PHP7.3RC2 + PCRE2 combination because I can't reproduce the problem in a VM.
Update 1: I couldn't find a good how-to guide to increase the stack size of the library.
Update 2: physical server has SELinux enabled. I will investigate this way. For the time being, the PHP version was downgraded to 7.2.
If somebody has the same problem or any idea, please let me know.
