--- Re-run this test:
python3 tools/test.py -n vm-mac-debug-arm64 co19/LanguageFeatures/Subtyping/dynamic/generated/function_type_function_global_variable_A10_t01

https://dart-ci.appspot.com/log/vm-mac-debug-arm64/vm-mac-debug-arm64/755/co19/LanguageFeatures/Subtyping/dynamic/generated/function_type_function_global_variable_A10_t01

The change looks unrelated. The failure could be flaky as deflaking doesn't work at the moment.

I wasn't able to reproduce the crash locally (even with 2000 runs).
