TITLE

Segmentation fault with PHP 7.4 and ionCube 10.4.0

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Plesk 18.0.29 Update #1, Ubuntu 10.04.5 LTS, x64

PROBLEM DESCRIPTION

When running WHMCS v8 with PHP 7.4, I get segmentation faults.

STEPS TO REPRODUCE

Install WHMCS v8 and make it run with PHP 7.4

ACTUAL RESULT

Cron reports "segmentation fault", website does not work (502 bad gateway).

EXPECTED RESULT

Should work normally.

ANY ADDITIONAL INFORMATION

If I manually replace the ioncube loader /opt/plesk/php/7.4/lib/php/modules/ioncube_loader_lin_7.4.so with the newer version 10.4.1, everything works perfectly.

YOUR EXPECTATIONS FROM PLESK SERVICE TEAM

Confirm bug

I see it was updated to 10.4.2 with your PHP 7.4.10 release. Thanks!
Unfortunately, on the same day ioncube released version 10.4.3 with this changelog: "Fix for a regression in the 10.4.2 PHP 7.4 Loader which could lead to a zend_mm_heap corrupted error with WHMCS."
Damn...
