Even though the final tree dump looks correct this is a still a front-end
issue
as the front-end communicates the aliasing sets to the rtl optimizers.
I am going to take it too.

The code is illegal, and therefore gfortran can do anything
it wants (including start WW III).

Confirmed, fortran front-end needs to do something similar to the C front-end
