Harald Anlauf <anlauf at gmx dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |anlauf at gmx dot de --- Comment #3 from Harald Anlauf <anlauf at gmx dot de> --- (In reply to Andrew Baldwin from comment #2) > In 7.2.1.4 of my copy of the standard it states: > > "A subroutine defines the defined assignment x1 = x2 if" > > ... > > "(5) either > (a) the ranks of x1 and x2 match those of d1 and d2 or > (b) the subroutine is elemental, x1 and x2 are conformable, and there is > no other subroutine that defines the assignment." It also says: "If d1 or d2 is an array, the shapes of x1 and x2 shall match the shapes of d1 and d2 , respectively." This is not the case for your example. (NAG and Crayftn also do not reallocation.) > Since x1 and x2 are not conformable in this instance the defined assignment > (overloaded assignment) my reading is that it should not occur. I'm no standard expert, but (5)(a) appears to be satisfied, so the non-conformance of x1 and x2 does not matter. To be sure, consider posting your question on comp.lang.fortran.
