// This test checks the compatibility of the interaction between `--emit obj` and
// `#[global_allocator]`, as it is now possible to invoke the latter without the
// allocator shim since #86844. As this feature is unstable, it should fail if
// --cfg check_feature_gate is passed.
// See https://github.com/rust-lang/rust/pull/86844
//@ ignore-cross-compile
// Reason: the compiled binary is executed
