Description
I tried this code:
#[allow(unconditional_panic, unused)] // for minimal test case; doesn't cause problem
fn main() {
1 / &0;
}I expected to see this happen: program panics with main.rs or the actual location on disk of the standard library source code file that caused the panic given as the location
Instead, this happened: program gives /rustc/eb26296b556cef10fb713a38f3d16b9886080f26/library/core/src/ops/arith.rs:484:1 (internal compiler location?) as the panic location

Backtrace
No build errors, but the backtrace for the program also contains references to internal compiler locations that I would expect to point to the actual locations of standard library source files on disk, as well.
