This is a follow up to #200815 and #184634. The PCRE2 JIT SEAlloc does not support the `fork()` as announced in their README [0]: > If you are enabling JIT under SELinux environment you may also want to add > --enable-jit-sealloc, which enables the use of an executable memory allocator > that is compatible with SELinux. Warning: this allocator is experimental! > It does not support fork() operation and may crash when no disk space is > available. This option has no effect if JIT is disabled. As a result using it in PHP can break apps and tools, it can only be enabled under very specific context where you have a full picture of what the PHP code is doing. This contribution disables again the PCRE2 JIT SEAlloc and extends the existing PHP/PCRE2 tests to make sure we do not enable it again by mistake. [0] https://www.pcre.org/readme.txt
