Summary0002310: xdebug 3.4.0 crashes php8.1-fpm after script execution
Description

After upgrading to xdebug 3.4.0, php8.1-fpm crashes after script execution with either SIGSEGV (11) or SIGBUS (10)

[18-Dec-2024 11:57:07] WARNING: [pool www] child 46843 exited on signal 11 (SIGSEGV) after 6.086957 seconds from start
[18-Dec-2024 11:57:07] NOTICE: [pool www] child 46893 started

[18-Dec-2024 12:12:06] WARNING: [pool www] child 853 exited on signal 10 (SIGBUS) after 80.854785 seconds from start
[18-Dec-2024 12:12:06] NOTICE: [pool www] child 1248 started

According to xdebug traces i did to find out whats wrong, scripts were executed to the last line and then the crash happened.
Reverting xdebug to version 3.3.2 solved the problem.

Steps To Reproduce

Dont know how to reproduce or if that can be reproduced, after upgrading to xdebug 3.4.0 php8.1-fpm crashed randomly when trying to use the web application i am working on.
