That's what I thought, but this is normal and doesn't tell anything
about why the problem happened.  Hmm...

Is it correct that the character at buffer position 1295 is a newline?

Also, what are the values of the following?

  it->stack[0].current
  it->stack[0].string
  it->stack[0].method
  it->method

(The second one I expect to be a Lisp string or nil.)
