// In the following scenario:
// 1. The crate foo, is referenced multiple times
// 2. --extern foo=./path/to/libbar.rlib is specified to rustc
// 3. The internal crate name of libbar.rlib is not foo
// Compilation fails with the "multiple crate versions" error message.
// As this was fixed in #17189, this regression test ensures this bug does not
// make a resurgence.
// See https://github.com/rust-lang/rust/pull/17189
