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.
