vmstat -m and netstat -m dumping core when run on vmcores

Hi,

I've noticed the following rebooting after a panic:

pid 41246 (vmstat), uid 0: exited on signal 11 (core dumped)
pid 47091 (netstat), uid 0: exited on signal 11

And indeed, trying to manually run those on the resulting vmcore makes 
them crash:

# vmstat -m -M /var/crash/vmcore.0
Segmentation fault (core dumped)
# netstat -m -M /var/crash/vmcore.0
Segmentation fault

Backtrace is below:

* thread #1, name = 'vmstat', stop reason = signal SIGSEGV
   * frame #0: 0x000000080026d19f 
libmemstat.so.3`memstat_kvm_malloc(list=0x00000008007c5000, 
kvm_handle=0x000000080070e000) at memstat_malloc.c:351

     frame #3: 0x0000000000204095 vmstat`_start(ap=<unavailable>,

Wonder if it's just me or something is broken here?
