Sorry, I investigated many cases, but I couldn't find it.

When this bug is reproduced, must be s == 0 and s1 > 0 and
d->newlines[s] != d->newlines[s1].  In addition, they mustn't be
updated until reaches a next newline.

I believe that all of them is never filled at the same time.  So I think
once I close the bug without fix.
