I've seen something similar.  When clicking on an error line in the 
*compile* buffer, Emacs sometimes jumps to the wrong line.  Then if I 
click on the same line again, it will jump to the correct line.  But 
without me doing anything, the window begins switching between the two 
positions (it may be the same file, or two different files), about once 
a second.  I can sit there and watch or hit C-g, but it keeps 
switching.  Only a kill buffer gets me out of it.
