What I meant was I first attempted to remove the `vm.debug == true` restriction and run the tests on the release VM. But then found the missing CICrashAt option to be the issue that made them fail with "did not crash, expected it to crash" errors. So I assumed that was the only issue, and if that were solved, we could just reuse all tests for the release VM.

Okay.
