Dart VM version: 2.2.0-dev.0.0 (Mon Nov 19 15:10:42 2018 +0100) on "linux_ia32"
OS/Kernel: Linux 3.2.0-4-686-pae #1 SMP Debian 3.2.73-2+deb7u3 i686

Internal Error: The compiler crashed when compiling this element.

The compiler is broken.

When compiling the above element, the compiler crashed. It is not
possible to tell if this is caused by a problem in your program or
not. Regardless, the compiler should not crash.

report this problem at http://dartbug.com/new.

Please include the following information:

  • the name and version of your operating system,

  • the Dart SDK build number (2.2.0-dev.0.0), and

This appears to be a crash from the CFE.

@generic13 - to help us investigate, could you provide us with a small example program that would let us reproduce the issue locally?

Thanks for the great repro @generic13 !

@peter-ahe-google or @askeksa-google - looks like a case where a compile-time error was not properly propagated within fasta?

I'm not able to reproduce this crash on top-of-tree. I did fix some issues in this recently, and I notice that @generic13's SDK is a few months old. I'll see if I can reproduce this with an older SDK. @generic13 did you download the SDK from dartlang.org?

I'm not sure what is going on here. I was able to find version 2.2.0-dev.0.0 on Archive | Dart.

However, this is not the most recent version of the Dart SDK. That version is 2.1.1-dev.3.2. I think 2.2.0-dev.0.0 might be a mistake in the release process.

@generic13 I recommend that you install a newer version of the SDK.

I can reproduce the second stack trace 2.2.0-dev.0.0, but the error is reported correctly in 2.1.1-dev.3.2:

test2.dart:1:23: Error: 'A' is already declared in this scope.
part of my_lib; class A{}
                      ^
test.dart:1:23: Context: Previous declaration of 'A'.
part of my_lib; class A{}
                      ^

I can reproduce the first stack trace if I add a lot of comments to test2.dart before the declaration of A in 2.2.0-dev.0.0, but again, the error is reported correctly in 2.1.1-dev.3.2:

test2.dart:195:7: Error: 'A' is already declared in this scope.
class A {}
      ^
test.dart:3:7: Context: Previous declaration of 'A'.
class A {}
      ^

Sorry for a delayed response, emails got caught in spam. Yes, there were a lot of comments, since it's a generated code. With a small test case, the compiler emitted a message before crashing, but with lots of comments, the compiler crashed with no message that would indicate the cause of crash.

I did download from dartlang.org, I'll try again with the newer build.

The newest version generates a correct error message and does not crash for either the short or large test case.
Thank you!
