PHP-FPM Signal 11 (SIGSEGV) with Tracy Debugger bluescreen

[nloyola]

I am using ProcessWire 3.0.242 on Debian bookworm, with PHP 8.3.14 and NGINX 1.22.1. I have TracyDebugger 4.26.45 enabled. 

Very recently, php-fpm reports a signal 11 when I have a PHP ParseError (or any other type of error). This causes NGINX to display a "502 Bad Gateway" page. If I disable Tracy Debugger, I see the Fatal Error screen in the browser. Does anyone know how to fix this problem?

This was not happening a few weeks ago. Before, I would see the Tracy Debugger bluescreen displaying the error.

I have tried the following but still have the problem:

• increasing the Tracy Debugger "Reserved memory size"
• disabling opcache
• increasing the php-fpm memory limit
• using previous versions of Tracy Debugger

Any help would be appreciated.

Thanks

The issue was that I was using Xdebug 3.4.0. When I downgraded to Xdebug 3.3.2 it started working like before.
