keyword not allowed for ISO_C_BINDING intrinsic
gFortran and ifort allow this to reduced test case to compile without warning
or errors.
Flang front-end does not accept it.
[naromero@naromero-desktop bugs]$ flang -c optional_arg.F90
optional_arg.F90:8:30: error: Keyword 'shape=' may not appear in a reference to
a procedure with an implicit interface
call c_f_pointer(cptr,iptr,shape=(/csize/))
I understand the error -- but if you are using an intrinsic from the
iso_c_bindings, shouldn't the procedure interface be considered explicit.
