canonicalizing paths on RAM disks fails

[xNxExOx]

I was trying to build tokio example but I encountered these errors. I tried both discord for Rust Programming Language, and tokio gitter, where I was told it is compiler error.
I have Windows 10 1803 in Czech language, so "Nesprávná funkce." would be something like "Invalid function." in English.

code example from:

A:\ is my RAM drive, why output folder can not be on RAM drive?

Rust currently insists on canonicalizing paths, which unfortunately does not work on certain types of drives. To fix this libstd would need to gain a way of normalizing paths without canonicalizing them, and then rustc would be updated to use that everywhere.

Triage: This is about problems canonicalizing paths on RAM drives. So is #48249, so closing as duplicate.
