Low priority. Happy to fix it but need some advice on what stage would be best suited to detect this:

interface foo_intf;
endinterface

module submod
(
    input logic a
);

endmodule

module t (/*AUTOARG*/);
    foo_intf the_foo;

    submod
      submod_inst
     (
	.a (the_foo) //Oups! This is not the interface port
	);
endmodule

Causes:
%Error: Internal Error: t/t_interface_type_bad.v:11: ../V3LinkDot.cpp:1253: Bad alias scopes

https://github.com/phb/verilator-dev/tree/improve_interface_errors branch makes interfaces more resilient to internal errors and gives better error messages when used incorrectly.
