Trying to build Dart after clean checkout from SVN gives me :

runtime/vm/dart_api_impl.cc: In function ‘void* dart::Dart_CreateIsolate(void*, void*)’:
runtime/vm/dart_api_impl.cc:38:71: error: declaration of ‘void* dart::Dart_CreateIsolate(void*, void*)’ with C language linkage
runtime/include/dart_api.h:185:26: error: conflicts with previous declaration ‘void* Dart_CreateIsolate(const Dart_Snapshot*, void*)’

I ended up changing the dart_api_impl.cc declaration to use const Dart_Snapshot* and did a cast to (void*) in order to call Dart::CreateIsolate((void*)snapshot, data);

in r330, the "conflicts with previous declaration"-type errors are gone, however the "variable ‘X’ set but not used"-errors still occur with gcc 4.6.1 (prerelease on arch linux)

Could you revoke the classification of issue #9 as a duplicate, then? Issue #9 has been merged into this issue here, and it has not been fixed.

See: b/374689139.

https://dart-review.googlesource.com/c/sdk/+/390941 is blocking an SDK roll.

Root cause:


```
Action threw an exception: type 'ConstructorMember' is not a subtype of type 'ConstructorFragment' in type cast
#0      InterfaceTypeImpl.constructors2.<anonymous closure> (package:analyzer/src/dart/element/type.dart:569)

#9      _Visitor.visitConstructorDeclaration (package:linter/src/rules/prefer_const_constructors_in_immutables.dart:58)
```


To verify the fix locally:

```
  solo_test_X() async {
    await assertNoErrorsInCode(r'''
class A<T> {}
''');

    var A = findElement.class_('A').instantiate(
      typeArguments: [intType],
      nullabilitySuffix: NullabilitySuffix.none,
    );
    A.constructors2;
  }
```

…terrupted

Thread interrupts can be disabled after thread interrupter decided to
interrupt a thread but before thread actually receives and handles
a signal.

This may cause a data race accessing a Sample between profiler which
initializes and adds a Sample and the main thread using
Profiler::sample_block_buffer() in the profiler unit tests.

This is a possible fix for the following benign TSAN error:

This test has a few independent calls to asyncExpectThrows which uses
asyncStart/asyncEnd. However, multiple top-level asyncStart/asyncEnd
are not allowed, which causes the following flaky error:

```
Unhandled exception:

--- Re-run this test:
python3 tools/test.py -n vm-aot-ubsan-linux-release-x64 standalone/io/http_auth_digest_test
```

This change attempts to fix this by adding a top-level asyncStart/asyncEnd
and also asyncStart/asyncEnd to the server start/shutdown to
enclose each test case into asyncStart/asyncEnd and avoid printing
"unittest-suite-success" marker before all test cases are finished.
