// Compiling Rust code twice in a row with "fat" link-time-optimizations used to cause
// an internal compiler error (ICE). This was due to how the compiler would cache some modules
// to make subsequent compilations faster, at least one of which was required for LTO to link
// into. After this was patched in #63956, this test checks that the bug does not make
// a resurgence.
