Re: RFA: Revamp fortran array types

[ aliasing in Fortran ]

It would be really good if somebody could check with the fortran gods if this is or isn't the case.

I tend to put it this way (note that the Standard is mostly about restrictions on what *programmers* can do, not what the compiler is required to do):

Two names must not refer to the same or overlapping storage unless you, the programmer, indicate that they do (by either using EQUIVALENCE or designating the storage with the TARGET attribute).

HTH,
