I think "case.struct_supergroup NOT present!!!" can be ignored and is 
not a problem in this case, since it looks like you specified the 
symmetry operation instead as:

Program input is: "1.0 0.0 0.0 0.5 0.0 1.0 0.0 0.5 0.0 0.0 1.0 0.5 "

I think the problem is how you specified the input, which results in the 
error "Fortran runtime error: Bad integer for item 1 in list input".  
This is because you have used real numbers like "1.0" in places where 
you need to use integers like "1".  So the input likely needs to be:

Program input is: "1 0 0 0.5 0 1 0 0.5 0 0 1 0.5 "
