PHP CLI with Symfony causing Program received signal SIGSEGV, Segmentation fault

Description

I have been doing a simple study into the api-platform. Until today, everything was working fine, but then I upgraded the packages on my computer by running

sudo apt-get update && sudo apt-get upgrade

The upgrade also happened to update my php as seen below from running the command cat /var/log/apt/history.log

Currently, my php version is as follows

PHP 8.1.9 (cli) (built: Aug 15 2022 09:39:52) (NTS)

Now, when I run my the command symfony console list at the root of symfony project I get

signal: segmentation fault (core dumped)

Thanks to this question, I was able to run this command gdb $(which php8.1) and then I typed run [project_path]/bin/console and got

I am no C or C++ developer, so I am not sure what the error means exactly, apart from No such file or directory part.

I would appreciate any help here. Thank you

Looks like an Xdebug issue. Try with that extension disabled.

@derickr ?

[iluuu1994]

@kellyjoe256 The problem seems to occur in xdebug_str_internal_addl. Can you try without Xdebug? If the problem disappears report the problem at https://bugs.xdebug.org.

[kellyjoe256]

Thank you, @damianwadley and @iluuu1994, it seems the issue was being caused by xdebug.

After disabling it, everything is working fine again. I am going to report the problem to the xdebug team.

[derickr]

FWIW, the Xdebug bug report is not useful, as it does not include a reproducible case.
