--- Comment #3 from H. Peter Anvin <hpa at zytor.com> ---
I'm confused about the fix.  Where do we access ->text[1] without having
examined ->text[0]?  It seems very dangerous, although I somewhat suspect that
the real problem is that we should not generate the type of token we currently
create for an empty string.
