Start by reproducing the failures in expected_coroutines_test with GCC 15, focusing on Expected.CoroutineSuccess, CoroutineFailure, CoroutineAwaitUnexpected, and CoroutineReturnUnexpected. Read folly/Expected.h around line 1621 and compare the coroutine behavior with a supported compiler. Done means the listed coroutine tests pass without the storage_ assertion failure under GCC 15.
