Emacs from Git as of revision 4817a832f49, which corresponds to the
bzr trunk as of revision 103065, crashes in find_interval() when I
move around grep buffers:

Steps to reproduce:
1) Start ./src/emacs -nw in the top-level of the source tree
2) Do M-x grep-find RET emacs RET
3) Do C-x 0 to maximize the window with *grep* buffer
4) Move around with C-v/M-v until it crashes

This may be related bug #7920, but I'm not sure.
