Subject: bug#16433: Test case for newline cache corruption
Date: Tue, 27 May 2014 12:20:52 -0400

Here is some additional output which perhaps will be helpful.  I put
checks at the beginning and end of rmail-swap-buffers, and also
immediately before and after the call to buffer-swap-text.  I had these
checks print a message when the cache is OK, and print the character
positions on the cache is corrupted, giving the following.  Newlines are
absent from the cache starting with the one at position 952.

                                        Ken
