Below I've tried to provide a more precise testcase.


with cvs emacs of 20041226 do:

 emacs --no-init -nw /su:root@localhost:/tmp/tsta

type your root pwd

type 1234567890 and save the buffer

jump to a new buffer tstb type 1234567890 and save it

repeat this process about 4 times

you will get this question:

Buffer *tramp/su root@localhost* undo info is 417914 bytes long; discard it? (yes or no)

its not entirely consistent, but I tried several times and was able to
repeatedly evoke the problem. The size of the testbuffers doesnt seem
to matter much, I tried much larger buffers, and what matters is the
number of times you switch buffers and save them.

You probably dont need to be root of course either.
