-// run-pass
-// Test that we don't duplicate storage for a variable that is moved to another
-// binding. This used to happen in the presence of unwind and drop edges (see
-// `complex` below.)
-//
-// The exact sizes here can change (we'd like to know when they do). What we
-// don't want to see is the `complex` generator size being upwards of 2048 bytes
-// (which would indicate it is reserving space for two copies of Foo.)
-//
-// See issue #59123 for a full explanation.
