Hi all,

I build the following docker images with PHP and xdebug enabled, I always install the latest xdebug via PECL.

So, last week I triggered a build because of sec updates in core PHP which also resulted in xdebug 3.3.1 being installed.

After that fpm crashes (segfaults) started to appear running behind nginx.

The message in fpm was not useful, my syslog also popped a message.

Feb 21 09:18:52 pop-os kernel: [43485.637469] traps: php-fpm[642189] general protection fault ip:***** sp:***** error:0 in libc
.so.6[703a2fc32000+155000]

Googled it and it send me to a memcheck (which I did, thought my laptop was broken) but the next day someone else notified me of the same problem. Which meant it was not a me problem :)

I tried to do a rebuild, downgrade of php (thought it was PHP) and then started disabling modules.
When I disabled the xdebug extension the problem disappeared, so I was onto something.

What I did, downgraded xdebug to 3.2.2 for PHP 8.1 and PHP 8.2 and that also works fine, so happy community again.

PHP 8.3 is still running with the new version 3.3.1 and is throwing the segfaults...
