Confirmed still occurs in 6.2.1 on the following C++ code:

#include 
#include 
float f(std::vector& A, std::vector& B)
{
  __builtin_assume_aligned(A.data(), 64);
  __builtin_assume_aligned(B.data(), 64);
  return std::inner_product(A.begin(), A.end(), B.begin(), 0.f);
}

Compiled using -O3 -ffast-math -mavx2.

Confirmed still affecting GCC 6.2.1. Similar C++ example:

#include 
#include 
float f(std::vector& A, std::vector& B)
{
  return std::inner_product(A.begin(), A.end(), B.begin(), 0.f);
}

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67059

Bug ID: 67059
   Summary: gfortran --version output is inconsistent with the
rest of GCC
   Product: gcc
   Version: 6.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: fortran
  Assignee: unassigned at gcc dot gnu.org
  Reporter: rivanvx at gmail dot com
  Target Milestone: ---

On Debian unstable with GCC 5.2.1 20150723 from experimental, I get

$ gcc --version
gcc (Debian 5.2.1-12) 5.2.1 20150723
Copyright (C) 2015 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

and g++/gdc/gccgo shows analogous output. However, gfotran has a different
output

$ gfortran --version

which could be made more consistent with the rest of GCC. The attached patch
fixes the issue.
