// The information inside a .exe file contains a string of the PDB file name.
// This could be a security concern if the full path was exposed, as it could
// reveal information about the filesystem where the bin was first compiled.
// This should only be overridden by `-Clink-arg=/PDBALTPATH:...` - this test
// checks that no full file paths are exposed and that the override flag is respected.
// See https://github.com/rust-lang/rust/pull/121297
