On recent main, this test case fails verification with ``` SIL memory lifetime failure in @$s4main4doityyF: memory is not initialized, but should be memory location: %21 = struct_element_addr %20 : $*M4, #M4.s2 // user: %23 at instruction: %23 = apply %22(%19, %21) : $@convention(thin) (@inout S, @inout S) -> () [...] 4. While running pass #173 SILFunctionTransform "MoveOnlyChecker" on SILFunction "@$s4main4doityyF". for 'doit()' (at test/Interpreter/moveonly_reinit_noncontiguous.swift:32:1) ```
