            Bug ID: 57924
           Summary: -Werror -Warray-temporaries
                    -Wno-error=array-temporaries fails on array temporary
                    warnings
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jahns at dkrz dot de

source file to trigger the warning

When compiling a program that generates an array temporary, and the compiler is
instructed to

1. generate warnings for array temporaries
2. warnings are elevated to errors
3. array temporary warnings are explicitly set to non-errors

compilation still aborts once a corresponding warning is encountered.

I've attached a source file + Makefile to demonstrate.

I've also tested gfortran 4.6.3. All my tests were done on a Debian system.

Makefile giving flags

Add Makefile missing from original report.

My impression is that -Werror= is not properly supported by gfortran - only
-Werror by itself. (See also PR44054.)
