--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> --- This turned out to be a long-standing bug with split_nonconstant_init (since 4.7, apparently): initializion of individual elements of an aggregate are not a full-expressions, but split_nonconstant_init was making full-expressions out of them. My fix for PR66139 extended the use of split_nonconstant_init, and thus the bug, to aggregate initialization of temporaries within an expression, in which context the bug is more noticeable. This is a tricky one, getting back into the issues with cleanups not nesting properly that wrap_temporary_cleanups handles some of, but not this example.
