Reduced example:

struct Command<'s> {
    session: &'s (),
    imp: std::convert::Infallible,
}

fn command(_: &()) -> Command<'_> {
    unreachable!()
}

fn with_session<'s>(a: &std::process::Command, b: &'s ()) -> Command<'s> {
    a.get_program();
    command(b)
}

command: cargo check
Curiously, it doesnt ICE on the playground. Maybe it is OS-specific?

It's because we need -Cincremental enabled. I've got a fix.

Erase regions before doing uninhabited check in borrowck

~Also, fingerprint query keys/values when debug assertions are enabled. This should make it easier to check for issues like this without `-Cincremental`, and make UI tests a bit cleaner.~ edit: moving that to a separate PR

Fixes rust-lang#107505
