Jürgen Reuter <juergen.reuter at desy dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |juergen.reuter at desy dot de --- Comment #13 from Jürgen Reuter <juergen.reuter at desy dot de> --- Indeed I think that is a duplicate of pr71544. This here is definitely from the discussion on c.l.f. starting on June 6, 2016 under the title "Possible gfortran compiler optimization bug when dealing with c-style pointers", and the code in pr71544 is identical to the one posted there. The upshot of the discussion to me looks like that there was disagreement between Steve Kargl and Richard Maine whether the code is standard-conforming or not. I think, this is still not resolved.
