Well, TR 18037 doesn't do anything to change that, so if you define some target-specific way to use different types in certain circumstances then you're going outside what was allowed for in the TR. In the case of sizeof there's also the issue the same type being used for objects in different address spaces - how do you determine when sizeof (which can be a runtime operation when VLAs are involved) should return some different type because of address space involvement, or what type to use to store a VLA size at runtime? -- Joseph S.
