Silent crash of buzz parser when script ends with a comment

[Belkharym]

When a buzz script ends with a comment in its last line, the buzz parser (bbzparse and bbzc) will create an empty .basm file and stop without displaying anything on the terminal.
The bug happens in the following cases:

• The file contains only one (1) line with a comment (can have any amount of whitespace before it), without any new line after that.

  # Anything here, no new line after

  but if there is one (1) or more line (that doesn't only contains a comment, can be an empty line) before or after it, there is no crash.

  function foo() {
      # Do something
      return 1 + 2
  }
  bar = foo() # Blah Blah
  # Lets print something
  print("something")
  
  # The last line with just a comment

• The file ends with a statement directly followed by a comment and has no new lines after it

  # Buzz stuff
  foo = {.bar = 42}
  print("Something") # No line return after this comment

  But if you add a new line at the end of the file, it won't crash.
