Same principle applies.

The problem comes when we try to tsubst_copy_and_build the result of the
convert_like_real called at template definition time.

> build_aggr_init_expr isn't called at all here BTW, I just don't see too many
similarities with PR46003.

My point in discussing 46003 has been that the problem is
build_conditional_expr calling convert_like_real; build_aggr_init_expr isn't
the key.
