Identifying Commandline Arguments

For whatever it’s worth, my take is as follows.

Any processor that fails to detect and report a violation of a numbered constraint in the standard, “C934 (R927) If type-spec appears, it shall specify a type with which each allocate-object is type compatible,” as in the code below, does not conform:

   character(len=:), allocatable :: s
   integer, allocatable :: i
   allocate( character :: s, i )
end

Intel Fortran can thus be seen to have a bug:

gfortran conforms:
