Compiler panics using rls

[arturoc]

While using rls the compiler seems to panic with the following error message:

thread '<unnamed>' panicked at 'Forcing query with already existing DepNode.
- query-key: Canonical { variables: [], value: ParamEnvAnd { param_env: ParamEnv { caller_bounds: [], reveal: UserFacing }, value: Binder(TraitPredicate(<std::option::Option<rin::math::Point<f32, rin::math::U2>> as std::marker::Sized>)) } }
- dep-node: EvaluateObligation(a75bc336179bba2b-1b713f2a33709d71)', librustc/ty/query/plumbing.rs:531:9

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.30.0-nightly (5c875d938 2018-09-24) running on x86_64-unknown-linux-gnu

Some previous discussion in the RLS repo:

• 'Forcing query with already existing DepNode' panic on new nightly rls#1032
• thread '<unnamed>' panicked at 'Forcing query with already existing DepNode. rls#999

@arturoc do you have a project which causes this ICE? I'm trying to investigate but can't reproduce

[arturoc]

The project where i was getting those errors is too big and not public but i believe this might be related with re-exporting symbols. rin::math::Point in the error is actually https://github.com/arturoc/na Point being re-exported which in turn is re-exporting https://github.com/rustsim/nalgebra Point

I'm getting a similar error, in a similarly private large workspace project (module path edited):

thread '<unnamed>' panicked at 'Forcing query with already existing DepNode.

While it is not a huge issue for me right now, I thought it would be a good idea to just give you an example of the issue to investigate it.
I'm using VSCode 1.31.0
