// Regression test for issue 72154, where the use of AddressSanitizer enabled
// emission of lifetime markers during codegen, while at the same time asking
// always inliner pass not to insert them.  This eventually lead to a
// miscompilation which was subsequently detected by AddressSanitizer as UB.
