ICE from attempting to build cargo hello world on wsl filesystem but from windows

[lahwran]

Code

create a new cargo project in windows (I did this via jetbrains ui), then move it to //wsl$/... somewhere. try to run it with cargo run from windows. the windows rust compiler will likely crash with an internal error.

Meta

rustc --version --verbose:

I did this with jetbrains clion. its run output:

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 1.46.0 (04488afe3 2020-08-24) running on x86_64-pc-windows-msvc

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C incremental --crate-type bin

note: some of the compiler flags provided by cargo are hidden

query stack during panic:
end of query stack
error: aborting due to previous error

error: could not compile `milkrs-server`.

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

Process finished with exit code 101

This looks like common issue with remote filesystems ($wsl is remote filesystem with WSL2) like NFS, SMB, ...

Does it work if you run cargo clean after the move?
