[jakemac53]

Hmm, is this reproducible or did it just happen once? It seems like a possible kernel bug.

[natebosch]

What version of the SDK are you on?

What version of the build_* packages?

[jakemac53]

closing this for now, assuming it is stale. please respond with more info if it is still a problem

[softmarshmallow]

having this issue. pub upgrade does not work for me

[natebosch]

@softmarshmallow can you attach the output from pub deps?

What is the specific command you are running to see this stack trace?
