Verilog-mode

Just added the latest (v718) verilog-mode.el file to my Emacs path dir and now I get the following error when trying to expand AUTOs:

Wrong number of arguments: #<compiled-function (beg end) "...(15)" [beg end string set-text-properties 0 nil] 5 551036>, 3

Has anyone seen this before? I also got the same error when trying to use the AUTO_TEMPLATE function with my older (v538) version of verilog-mode.

The testcase I am using is very simple, and is as follows:

module auto_test ();

   foo f1 (/*AUTOINST*/);

endmodule // auto_test

File foo.v:

module foo(
       input [7:0]     blah,
       input [2:0]     blee,
       output [3:0] bar
       );

endmodule // foo
