[P-E-P]

ICE in rust/resolve/rust-late-name-resolver-2.0.cc:303, code hitting an assert about opening scope resolution.

[P-E-P]

derive-default & derive-eq-invalid : similar to https://github.com/Rust-GCC/gccrs/pull/3766, we're duplicating a node but keeping it's node id. This means there are two different usages with one node id.

I think I have a fix for some of these in my dev branch

Edit: nope, but I'll have some fixes out in a bit
