> Could anyone review this change that fixes https://bugs.openjdk.org/browse/JDK-8366118? When this bug happens, it is difficult or almost impossible to debug due to the lack of stack trace, hs-err log or core dump. Fortunately we are also experimenting with sigaltstack for https://bugs.openjdk.org/browse/JDK-8364654, and it helped immensely to identify the root cause.

> I will also try adding a test case for DontCompileHugeMethod under -XX:-TieredCompilation.
