I'm trying to use custombuild to build php7.3 and 7.4, but during the process it quits with the following error:

Code: 
Fatal error: Uncaught InvalidArgumentException: RegexIterator::__construct(): Allocation of JIT memory failed, PCRE JIT will be disabled. This is likely caused by security restrictions. Eithemission to allocate executable memory, or set pcre.jit=0 in /usr/local/directadmin/custombuild/php-7.4.8/ext/phar/phar.php:1133

The error suggests to set pcre.jit=0, but where do you set it? I assume in "a" php.ini. Which one does custombuild use during the build process?
 
I don't know anything about this but the error seems to suggest that it should be set in
/usr/local/directadmin/custombuild/php-7.4.8/ext/phar/phar.php
 
Then I guess the error message is incorrect because it says:

set pcre.jit=0 in /usr/local/directadmin/custombuild/php-7.4.8/ext/phar/phar.php
 
I found that one as well, and it gives the suggestion to add it to the php.ini (which one). I got around it for now by temporarily rebooting in a non grsec protected kernel. Luckily this is a test system.
 
Probably

/usr/local/php73/lib/php.ini
/usr/local/php74/lib/php.ini
