Can the calculation of allocated size be done in terms of uint64_t and
then we can easily check if the allocation is to exceed UINT32_MAX.

Then there are no changes to the API and the code doing this should
be a lot simpler and less prone to error.

This turned out to be a simple shortcoming of the validation test. This error case can happen also on 64-bit targets. There was no specification, API, and implementation change necessary, just a fix in the test code:
