Internal compiler error: mutex.rs could not find scope info

[cbcrouch]

Received the following error while compiling a test application in rust. If this looks like a geuine error I can provide source, stack traces, etc. if needed.

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

Thanks for the detailed report!

[michaelwoerister]

This is very likely a duplicate of #22432. I'm leaving it open for now.

[Ogeon]

A similar or the same ICE popped up in Rustful with today's nightly. The difference I can see is that it's reported for rwlock.rs.
