To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. https://3v4l.org/4YDGj If you've tried *that exact code* and it isn't working, - What version of PCRE2 do you have? - What if you disable JIT with pcre.jit=0?
