[macOS] Running a new Flutter app with Impeller on Coffee Lake CPU causes EXC_BAD_ACCESS: A bad access to memory terminated the process. #159278
Description
Steps to reproduce
I initially encountered this issue when trying to run the https://github.com/bdero/flutter-scene-example but have reduced the error to the simplest example possible
- Have a MacBook Pro 2019 (I assume any Mac with a Coffee Lake CPU would work) running the latest version of macOS (
15.1.1at the time of this writing) - You can choose to use either
stableormainbranch - Create a new Flutter project, using the empty or basic application.
- Enable native assets using
flutter config --enable-native-assets - Don't change anything and run
flutter run -d macos --enable-impeller
I'll note that I ran into this issue and even took the liberty of wiping my Mac to factory settings and doing a fresh install and still encountered this issue. I am using VS Code. Executing the run command from the native Mac terminal results in the same error.
Expected results
App runs without issue
Actual results
App never launches. Instead the following is output into the terminal:
Error waiting for a debug connection: The log reader stopped unexpectedly, or never started.
Error launching application on macOS.Code sample
Code sample
import 'package:flutter/material.dart';
void main() {
runApp(const MainApp());
}
class MainApp extends StatelessWidget {
const MainApp({super.key});
@override
Widget build(BuildContext context) {
return const MaterialApp(
home: Scaffold(
body: Center(
child: Text('Hello World!'),
),
),
);
}

Running via Xcode is perhaps where things get most interesting, as we receive an exception almost immediately while running that we can't get past
