-// Test to make sure that `<Box<T>>::default` does not create too many copies of `T` on the stack.
-// in debug mode. This regressed in dd0620b86721ae8cae86736443acd3f72ba6fc32 to
-// four `T` allocas.
-//
-// See https://github.com/rust-lang/rust/issues/136043 for more context.
-//
-// FIXME: This test only wants to ensure that there are at most two allocas of `T` created, instead
-// of checking for exactly two.
