Symfony / Psysh错误:该过程已通过信号“11”发出信号

I've been given a php project that uses Symfony and wanted to do something equivalent to Ruby's binding.pry in one of the views. However, I keep getting the

"The process has been signaled with signal "11"." error

and the server goes down. Just had a couple of questions on why this is happening...

  1. Can I bind into views?

  2. Am I referencing it correctly? My code below

require('../vendor/psy/psysh/bin/psysh'); //Path via composer.json ?>

Somewhere below where I want to bind...

<?php eval(\Psy\sh()); ?>
