Correct Build Version of Dart Editor:

Dart Editor (DEV) build 39285

Added Area-Pub, Triaged labels.

This is definitely a VM error.

Removed Area-Pub label.
Added Area-VM label.

Zach, can you please work with Sebastian to get the setup which is trying to allocate an array of length -6?

Set owner to @zanderso.
Removed Priority-Unassigned label.
Added Priority-High, Accepted labels.

I could not reproduce on Linux. Is it possible to share more detailed reproduction steps, e.g. a project on github or similar, or does this happen with every "pub get" on Windows?

Added NeedsInfo label.

It doesn't happen on Linux. It happens in Windows. I'm hitting this same issue and had to downgrade my SDK.

This comment was originally written by Sebastian.G...@gmail.com

It happens on no specific Project. It happens during every Pub operation (Get, Upgrade, Serve).

Iam using Windows x64 and a x64 Dart Editor. I Updated to bleeding edge today and it works.

I've begun investigating on Windows.

Added Started label.

I have accidentally opened a duplicate issue #20588.
It also happens if you start pub without arguments.
And it only happens on 1 of 3 PCs i'm using (all with Windows 7 64 bit).

Bernhard, Don, Sebastian,

We're having a bit of trouble reproducing on Windows. Would one or more of you be willing to put a different dart.exe in your sdk folder so we can try to get a stack trace?

Thanks!

I've just started getting this error too after upgrading. I'm on Windows 8 x64 though. I'm happy to put a different dart.exe in my sdk and send you a stack trace if it helps.

Issue #20588 has been merged into this issue.

@Zra: sure please send me the other dart.exe and i will try it. But unfortunately i won't be at the PC where it crashes for the next couple of hours.

Please try dropping this dart.exe into your sdk bin directory. It should generate a dart stack trace before failing as before.

Attachment:
dart.exe (8.05 MB)

Okay done. I don't know if it is good or bad news - but it runs perfectly fine with the new executable. I have reverted the dart.exe and the old one still fails.

Bernhard, could you try with the latest built bit (not officially released yet) and report? Ideally you can install this one side-by-side with the failing setup. Thanks!

Bits are available here: http://gsdview.appspot.com/dart-archive/channels/dev/signed/39442/editor/

Here are the results, i also downloaded 1.6.0-dev.9.5 ...

1.6.0-dev.9.3: CRASH
1.6.0-dev.9.5: NO ERROR (the latest available build from the dev channel)
1.6.0-dev.9.6: NO ERROR (the link you have sent me)

So it seems the error is gone, at least on my PC.

Bernhard, could you try to collect a core dump for us? Running pub from the command line, after the assertion fails, but before clicking away the crash dialog:
1.) Run the Task Manager
2.) Right click on dart.exe
3.) Select "Create Dump File"

Thanks!

Here is something very strange! I have downloaded the zip-file of build 39285 which should be 1.6.0-dev.9.3 right? The big surprise is that this one is working too!

The dart.exe from the new download is 8462336 bytes in size.
The dart.exe from the old download is 8393728 bytes in size.

To be clear, both versions are 1.6.0-dev.9.3 but the one that is failing was an auto update from 1.6.0-dev.8.0 i think.

@mit-mit Why did you assign this back to pub?

Aside: should we remove the label Area-Pub, now that pub has its own repo?

Yes please!

I deprecated Area-Tools as it had a bunch of active issues no one was actually paying attention to. The majority of those were infrastructure issues that I moved to Area-Infra, but there were just a few like this that needed to go somewhere else.
