Consider enabling the flag chain-stack-traces to receive more detailed exceptions.
For example, 'dart test --chain-stack-traces'.

stderr:
Unhandled exception:
Dummy exception to set exit code.

There are multiple failures:

• Compile-time error is also seen on other bots, probably something is not copied when bots are sharded.
• ASAN error is likely related to the recent Clang roll (/cc @rmacnak-google).

Attempt to fix the test: https://dart-review.googlesource.com/c/sdk/+/363940.

[alexmarkov]

Compile-time error is fixed, but the test is still failing due to ASAN error.

[rmacnak-google]

ASAN looks upset that the profile is about to dereference 0. Seems like #52814, but for CallRuntimeEntry(kMemoryMoveRuntimeEntry). This seems to use CCallInstr instead of LeafRuntimeScope::Call, and skips things like updating Thread::vm_tag_ to inform the profile we're not running Dart anymore.
