I never claimed that the addressed value would be incremented, and that is not what is being discussed here, even though that too would have been a problem.

The thing is, at some point the compiler must calculate the address where to store the value. The question is then if there is a sequence point between calculating the data to store and the address which to store to. Otherwise there is ambiguity and the result is undefined.

According to http://en.wikipedia.org/wiki/Sequence_point there is no sequence point because of assignment (only initialization which this is not)

Btw was it you that downvoted my comment?
