Testcase

Found while looking into pr118580.  The argument of minval/maxval may be
evaluated more often than expected.

The attached program prints:

           4           0
           4           0
           6   0.00000000    
           5   0.00000000    
           6   0.00000000    
           5   0.00000000    

Expected:

           4           0
           4           0
           4   0.00000000    
           4   0.00000000    
           4   0.00000000    
           4   0.00000000    

The latter is confirmed by other brands (e.g. Intel).
