abort in find_interval

[Eric Hanchrow]

This has happened twice in a row; I don't yet know if I can reliably
reproduce it.

Here's what I remember that might be pertinent:

I was editing a buffer that was in cperl-mode.  The buffer had exactly
one formfeed character, and thus was logically two pages.  I'd created
a clone buffer with clone-indirect-buffer; in one of the buffers, I
had narrowed to the second page, and in the other buffer, I'd narrowed
to the first page (I do this occasionally; it's a convenient way to
work on the two pages separately).

In one of the pages, I'd just done C-k to kill some text.

Here's the backtrace:
