Error displaying a StaticArray

[cdsousa]

I'm getting this error in the vscode julia repl:

julia> using StaticArrays

After this happens, it won't execute any code within files (only within REPL).

[aviatesk]

yeah, we may want to keep handle_message living even after an internal error like this occurs (we actually do this for development mode: https://github.com/julia-vscode/julia-vscode/blob/master/scripts/packages/VSCodeServer/src/VSCodeServer.jl#L196-L212).

I think we should make sure we have try catch blocks around every piece of code where we call out to user code (so that we don't crash when there is a bug in some code that we didn't write). But for all of our code, we should crash if there is a bug and send a crash report, so that we can fix it. That at least has been the philosophy for us so far.

[cdsousa]

But the actual source of this specific error was something about vscode extension that is/will be investigated, or is it something with StaticArrays?

[cdsousa]

That error is now happening to me very frequently so I have restart Julia REPL dozens of times per hour. Is this something I can try to fix?

[davidanthoff]

This is a bug in the extension, we should not crash, even if there is a bug in StaticArrays.

[pfitzseb]

FWIW, the original bug seems to be fixed on master.

[aviatesk]

I guess without #1344 this error would happen for non-dev mode.

[pfitzseb]

Ah, makes sense. Didn't realize we were branching on that.
