Bug report

Hi @ondrejmirtes, I have an exit code 139 since the last version.

I tried to debug and

• I don't have the issue with the commit 787fc44
• I have the issue with the commit 958a525

This would mean that the issue is directly related to the commit phpstan/phpstan-src@85ab8cf

Code snippet that reproduces the problem

I succeed to reproduce something with
https://phpstan.org/r/045f28d0-facb-4537-8e7b-4338d354f611

But you need to remove the line /** @phpstan-var T $tgItemToKeep */.

Expected output

No errors
