Internal compiler error/panic while running rls #160

marcusball · 2017-01-27T21:48:51Z

I've finally succeeded in getting rls to run, and be accessible by the rls_vscode plugin, however, once it's run, it appears to be experiencing a compiler error while building term-painter. I cloned term-painter and verified that I can build it through cargo separately.

My rust toolchain is:

nightly-x86_64-pc-windows-msvc
rustc 1.16.0-nightly (df8debf6d 2017-01-25)

The full panic is:

Could you try running RUSTFLAGS=-Zsave-analysis cargo check please? That should fail with the same error. Could you let me know which crate is being built when it crashes and ideally give me a link to the source code so I can reproduce? Thanks!

FTR, this is a rustc/save-analysis bug. I'll investigate.

After looking at cargo tree, the term-painter dependency is coming from Rocket. Running cargo check in rocket's /lib directory does produce the same error:

To learn more, run the command again with --verbose.

I can't share the crate I'm writing right now, but, I verified I get the same error if I try to use VSCode on the main Rocket library (code ~/Rocket/lib).

Term painter is https://github.com/LukasKalbertodt/term-painter (I'll investigate this during the week)

marcusball · 2017-01-30T18:21:24Z

Alright, I appreciate you taking a look at it. Would it be better for me to bring this issue over to the term-painter repo, or perhaps rustc since the error itself says it's a compiler bug?

nrc · 2017-01-30T18:25:59Z

Nah, here is fine. It'll be me fixing it in any case and there's already info here.

@nrc,
Did you check it?

yes, though not in the RLS - thus "should"

I'm not sure if it is in nightly yet.
