Problem

Tracked in flutter/flutter#105609.
The test runs three times in https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8811953967788831233/+/u/run_build_ios_framework_module_test/test_stdout and the first two times fails.
Expected behavior
Actual behavior
Exit 255, error message is just a .
