This change adds a test to ensure we properly handle super calls in mixin that override initializers. This is a regression test for https://github.com/dart-lang/sdk/issues/44636, which happened to trigger a stack-overflow in ddc. The issue existed for a long time, but was fixed in a recent CFE change https://github.com/dart-lang/sdk/commit/52db62dd65284192755906691baf66c47a43f47e Change-Id: I7d4aceb8e313f0000e32d9550f301792a9ab84cd Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/178900 Reviewed-by: Nicholas Shahan <nshahan@google.com> Commit-Queue: Sigmund Cherem <sigmund@google.com>
