Summary0001893: Crash with ext-fiber and xdebug.mode=coverage
Description

When running tests for Amp v3 using ext-fiber, I get a BAD ACCESS in xdebug_create_key_for_path when collecting code coverage.

Steps To Reproduce

Install ext-fiber, https://github.com/amphp/ext-fiber. (Like most PHP extensions, phpize, ./configure, make, make install).
Set xdebug.mode=coverage
Clone https://github.com/amphp/amp, checkout v3 branch.
composer install --ignore-platform-reqs
Run vendor/bin/phpunit --coverage-text
