 Hi Dave,
 
 I'm faced with abort in "kmem -i" command with some vmcores
 and looking into it, but I haven't found the cause so far.
 Could you possibly take a look at this issue?
 
 I attached the abort log. I can send you the core and vmcore.
 
 Depending on execution, the occurrences vary.
 
 * abort, <segmentation violation in gdb>, or no problem
 * If not reproduced with interactive "crash> kmem -i", you may
   reproduce it with "echo 'kmem -i' | crash vmlinux vmcore".
 * observed in "kmem -V" and "kmem -z" as well
 * also observed on i686 with kernel 4.14 vmcore
 * latest crash (1926150e)
 
 Thanks,
 Kazu 
Just send me a pointer to the vmlinux/vmcore pairs (offline).
Dave
