--- Comment #4 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- Am I correct to summarize (simplify?) your expectation (interpretation as: use the overloaded assignment if the lhs and rhs are conforming, otherwise use the intrinsic assignment? If yes, what the compiler should do if some bounds are only known at run time? I agree with the first comment of Ian Harvey at https://groups.google.com/forum/#!topic/comp.lang.fortran/Vk4D8iDZOdc. I have no opinion for the second test in the above thread, beside a "don't do that!". If you think it is a gfortran bug, please file a new PR and, if possible, outputs from other compilers you have access to.
