But it would be helpful to provide an example, so that we can test the 
fix.  As Brian told you, your fix was no good:  it was not against the 
current code.

Then the bug is also in your code, for sending lines that are too long. 
  R shouldn't crash on user error, but "don't do that" is an appropriate 
response.

Then swig should be modified to produce valid code.

If you aren't interested in being helpful by testing fixes for your 
code, then I doubt if any of us are going to go out of our way to help 
you with your errors.
