Extension crashes on undefined functions

[Zankaria]

If the extension finds an undefined function anywhere in the code, it crashes. A formatting extension should still be able to format the callsite without crashing.

  "--using-cache=no",
  "--format=json",
  "--config=/home/zankaria/Projects/vichan/.php-cs-fixer.php",

how to reproduce this issue?

[Zankaria]

I downloaded vichan mainline, installed php-cs-fixer with composer require --dev friendsofphp/php-cs-fixer --ignore-platform-req=ext-gd --ignore-platform-req=ext-bcmath, configured the VSCode extension to point to the installation in vichan/vendor/friendsofphp/php-cs-fixer/php-cs-fixer, and tried to run it on any project file.

Should I perhaps reopen this issue in the php-cs-fixer repo?
