Here you are. I tried to print other variables too, but unfortunately,
when doing that it seems that I have killed the gdb session (doing `p
*p' has caused gdb to get locked telling "value has been optimized out",
and then I had to do `M-x signal-process RET shell RET 3 RET' to exit
from this.

--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
(gdb) p p
$1 = <optimized out>
(gdb) p end
$2 = (unsigned char *) 0x9bbcd354 <Address 0x9bbcd354 out of bounds>
(gdb) p obj
$3 = 12579352
(gdb) p name
$4 = <optimized out>
(gdb) p *p
(gdb) value has been optimized out
--8<----8<----8<----8<----8<--  end  -->8---->8---->8---->8---->8----

I will try to reproduce the crash... sorry for I lost the session...
