The following code ICE's on nightly and beta, but does not ICE on stable:

include!(line!());

For an example that doesn't give an immediate compile error (but later on bc it can't find the file):

include!(concat!("help-files/", file!()));

The ICE looks like:

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
