If it isn't related to php-src, do you know where should it be reported? I have absolutely no idea about the build process or why they use a different version of pcre or anything than the one they should use. Thanks for your help. ------------------------------------------------------------------------ [2021-01-30 13:52:58] cmb@php.net Thanks for the swift reply! It seems that Ubuntu didn't backport the fix for bug #79846[1].

I have tested the following in 2 builds of PHP-7.4.14, one from Ubuntu 18.04 repository and another one build with phpbrew. Unfortunately the results are different. I think phpbrew is correct. Test script: ------------ echo(preg_replace('/[^\p{L}\p{Arabic}]/', '0', '<->')); Expected result (phpbrew): ------------ 000 Actual result (ubuntu): ----------------------- <-> Should this be opened again or it needs to be reported elsewhere? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
