So the pointer is invalid. That is probably one of the ->next fields in
usrloc records list.
Can you go to frame 1 and print ptr there:
frame 1
p *ptr
The interesting file should be the ptr->next.
If it is not 0x696c2f36, then print *ptr->next, then *ptr->next->next
until it gets the ->next value 0x696c2f36. I wonder if there are other
invalid values on the ptr, or just ->next.
Cheers,
Daniel

thing, give also the output for:
p *ptr
in frame 0, if not printed by the bt full.
(gdb) frame 0
