test case
Hi,
The attached test case, slightly modified from an original by Alberto F.
Martin-Huertas in https://gcc.gnu.org/ml/fortran/2014-10/msg00124.html, changes
behaviour across versions; in particular, 4.7.3 seems correct and all other
versions I tried are not.
According to Steve Lionel https://software.intel.com/en-us/forums/topic/534799
the current Intel and gfortran behaviour is wrong, and this is also my
impression.
We have not had a definite answer at
https://groups.google.com/forum/#!topic/comp.lang.fortran/aFNK3FXqTUA
Again, my reading of the standard is that 4.7.3 is correct and the others are
wrong, but of course I will gladly accept a correction; either way, at least
one version of gfortran is wrong.
