(gdb) pr

At this point, gdb didn't respond anymore, so I hit C-c after a while.
I tried to get the recent keys using `xvector-elts' as suggested in
etc/DEBUG:

(gdb)     define xvector-elts
Type commands for definition of "xvector-elts".
End with a line saying just "end".
[...]
(gdb) xvector-elts recent_keys recent_keys_index 10
$2 = 137601148
$3 = (struct Lisp_Vector *) 0x833a078
0
$4 = 137554121

Hm, the session seems useless now, isn't it?  I'm sorry that I
couldn't provide more information.

Bye, Reiner.
