These pairs of files have caused crashes of GNU diffs:

NEWS.~13~		NEWS.~14~
diff-p1003.letter	diff-p1003.letter.~3~
diff-NEWS		diff-NEWS.~11~

Probably a bug in the basic algorithm implementation.

Other bugs and needed features noted at head of file diff-new.c

This pair of files is a minimal standard test case:

diff-test-from.text	diff-test-to.text

Suggest running against a Unix BSD diff, and using (compare-windows) in
GNU Emacs to find any differences.
