The error is caused by the use of the keyword "task" without defining it as a task. To fix the error, you can define the print_structs function as a task using the "task" keyword before the function definition. Here's an example:

module test;
    typedef struct packed {
        logic [9:-1][2:0] a; ///REQ-EXT-10001, REQ-EXT-10004
    } ST1;
    
    typedef struct {
        ST1 st1;
        ST1 st2[2:0];
    } ST2;
    
    task print_structs(ST2 s);
        $display("ST1:%p", s.st1);
        foreach (s.st2[i])
            $display("ST2[%0d]:%p", i, s.st2[i]);
        $display("%", s);
    endtask
    
    initial begin
        ST2 st2;
        st2 = '{2'b01, '{3'b1, 3'b0, 12'b1}};
        print_structs(st2);
    end
endmodule

In this code, the print_structs function is defined as a task using the "task" keyword before the function definition. The rest of the code is the same as before. This should fix the syntax error and allow the code to compile without errors.
