--- Comment #1 from janus at gcc dot gnu.org ---
I tried the test case with all gfortran versions from 4.7 to current trunk
(pre-7). All of them exhibit the same behavior, compiling the code without any
problems and giving the following runtime output:

 square(   2.00000000     ) =   -100.000000    
 square(   2.00000000     ) =   -100.000000    

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
