I have seen this happen in a subroutine, where an array is used but
never assigned a value, in which case Fortran considers it a function
as an actual argument.

I don't think I believe you. Well, more like I do believe you, but I
think your description is potentially misleading. It can be read to
imply that failing to assign a value can cause this error. Let us be
clear that all forms of this error come from failing to dimension the
array - not from any other cause. Matters like how the array is used
change the symptoms of the error, but are not the actual cause.
