// The order in which "library search path" `-L` arguments are given to the command line rustc
// is important. These arguments must match the order of the linker's arguments. In this test,
// fetching the Wrong library before the Correct one causes a function to return 0 instead of the
// expected 1, causing a runtime panic, as expected.
// See https://github.com/rust-lang/rust/pull/16904

//@ ignore-cross-compile
// Reason: the compiled binary is executed
