Summary0001549: Segfault during Drupal Installation.
DescriptionThe installation of Drupal 8.6 with the config_installer module fails reliably when xdebug 2.6.0 or 2.7.0alpha1 is enabled.
The error doesn't occur if xdebug.default_enable is disabled.
In the "Additional Information" section you'll find the excerpt of the core dumps I was able to create.
Unfortunately that's all information I can provide at this time - I hope it allows to isolate a possible error location.
Steps To ReproduceUnfortunately I wasn't able yet to dumb down the code to trigger the issue.
Additional Informationxdebug 2.6.0

Program terminated with signal SIGSEGV, Segmentation fault.

Hi!

From just the back trace I don't think I can find the problem. Would you please try the latest Xdebug beta for PHP 7.3 (2.7.0beta1) and see if the problem persists? If it does, I am going to need a way to reproduce this issue myself locally in some way. Please provide instructions in how to do that (without docker).

cheers,
Derick
