Memory leak due to wrong main function signature

[anjalismith]

As discussed in today's weekly meeting, we discovered that the following program causes a memory leak because the main function is missing the cin argument:

main ( cout : & Int ) -> () =
//main : &Int -> & Int -> () =
  //fun (cint : &Int) (cout : &Int)
    after 10 , (cout : & Int) <- 65
    wait (cout : & Int)

We commented out the lines of code that would make the program correctly print out the character 'A'. Currently, this program is printing output to cin.

Here's the error produced in runtests.log:

It's not desirable for users to encounter a memory leak when using the wrong function signature for main, and they should be notified through a different type of error with a communicative error message.
