I believe the N4323 paper Thiago cited is meant as a step in the direction of 
tightening (loosening?) the rules around the definition of data races, so 
writing the same value would be legal even if the writes conflict. But the 
summary doesn't say so, and I didn't have time yet to read the full paper.

If and when the execution model is thus changed, we can assume that older 
compilers will respect it, too, and use it. But I agree we can't until then.
