undefined method Closure::call()

[klepsydra]

What is the best version that still works with Symfony 2.8.3 and PHP 5.5.9?

./bin/ppm -vvv start --bridge=HttpKernel --host "0.0.0.0" --port 9090 --workers 1 --app-env "dev" --debug 1 --logging 1 --bootstrap=symfony

I keep getting:

Outch. Closure::call is only available as of PHP7. Could imho be replaced by Closure:bindTo

ping @marcj

Please test if this works.

Confirmed fixed, thanks for the rapid response!

Now it loads further into an older issue, but unrelated to this, and probably more to do with my project:

Filter 'softdeleteable' is not enabled.
500 Internal Server Error - InvalidArgumentException
