Error description

I get this error when installing xdebug extension:

undefined symbol: ZSTR_INIT_LITERAL

Full output:

### INSTALLING REMOTE MODULE xdebug ###

1 error occurred:
	* Status: The command '/bin/sh -c install-php-extensions xdebug' returned a non-zero code: 1, Code: 1

I assumed the error appears because an alpha version of xdebug is installed, so I fixed de error explicitly installing Xdebug v3.2.2

RUN install-php-extensions xdebug-3.2.2

Nevertheless I think this error should be fixed.

Thanks :)

This is a rather old version: do you have the same issue with the most recent one (v.2.1.60)?

You are right, a simple docker pull fixed the issue.

Thanks for your time! :)
