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.

On keyboard.c:command_loop, line 1789,
current_buffer->mark_active => t
Vtransient_mark_mode => t
Vdeactivate_mark => nil
Vselect_active_regions => t
When line 1814 is reached, current_buffer->mark contains a marker that
points to no buffer
(gdb) p current_buffer->mark
$8 = 48498715
(gdb) pr
#<marker in no buffer>
so
Fmarker_position (current_buffer->mark)
returns nil, and so beg is assigned XINT (nil), which is a bug.
Now, shouldn't current_buffer->mark_active be nil if the mark points nowhere?

No; it's possible that the buffer-local variable mark-active has been
set but the actual marker hasn't been assigned yet. This was an
oversight on my part, and I've now checked in a fix.
Thanks.
