Yes, I fixed such a bug last year in November. Semantic could kill
buffers if you used the GNU Global database and had your files in a
buffer with a symlinked directory in between. If you recently updated,
this cannot be it, though.

Is is very hard to debug this stuff without a backtrace. You could use
something like this:

(defun my-print-bt ()
(let ((buf (current-buffer)))
(with-current-buffer (get-buffer-create "*kill-history*")
(let ((standard-output (current-buffer)))
(insert "-------------------------------------\n"
"Buffer to be killed: " (buffer-name buf)
"\nBacktrace: \n")
(backtrace)))
t))

Activate this function by doing

(add-to-list 'kill-buffer-query-functions 'my-print-bt)

and then try to reproduce your problem. As soon as you get a killed
buffer, search for its name in the buffer "*kill-history*" and post the
backtrace beneath.

Be warned that a *lot* of buffers get killed during Emacs usage, so this
*kill-history* buffer will get large pretty quick.
