1. emacs -Q
2. M-x ediff-regions-linewise, type RET twice to use *scratch* for both
   Ediff buffers (it doesn't matter which buffers are used).
3. Any attempt to mark a region, indeed it seems any further input at
   all, makes Emacs abort.  This is completely reproducible. Full
   backtrace attached.
