Segmentation Fault on OpenBSD 6.2

Hi,

I tried to run istatserver on OpenBSD 6.2 RELEASE, however, it fails to start with Segmentation Fault.

-- gdb becktrace
(gdb) r
Starting program: /usr/local/bin/istatserver

Database valid

Program received signal SIGSEGV, Segmentation fault.

Hm, it seems that kvm_open(NULL, NULL, NULL, O_RDONLY, NULL) returns NULL.
