You declared "proc_ints" as a variable and specialized a procedure. That 
is not correct from the typing point of view. We'd either need a new 
section type for procedure/function specializations or we ensure that 
the following works:

=== code begin ===
type
   generic TArrayProc<T> = procedure(arr: TArray<T>);
var
   proc_ints: specialize TArrayProc<LongInt> = @specialize 
ProcessArray<LongInt>;
=== code end ===

The same just without "generic" and "specialize". This is then Delphi 
compatible (except the fact that Delphi does not support global generic 
functions/procedures, but only generic methods).
