But it works properly all other arches

PHP Version

PHP 8.1+

Operating System

Alpinelinux

Start with the three failing tests under Zend/tests/fibers/ and reproduce them on the ppc64le Alpine Linux builder, comparing their output with other architectures. Trace the reported differences and verify that all three tests pass with the expected output on ppc64le Alpine Linux.
