This bug was fixed, but I don't know which one. (I think it even doesn't matter at all).

Added a regression test.

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 1.35.0-nightly (acd8dd6a5 2019-04-05) running on x86_64-unknown-linux-gnu

note: compiler flags: -C incremental

with latest nightly it does not crash anymore, so nothing more to do.

Fixes #60629

(accidentally removed the remote branch on github, therefore GH closed the other PR.)
