>Description:

/etc/rc.d/dhcpd start (and the equivalent when starting by hand) dumps
core.

Here's the tail end of a kdump showing where core is dumped:

 16815 dhcpd    RET   write 417/0x1a1
 16815 dhcpd    CALL  fsync(0x4)
 16815 dhcpd    RET   fsync 0
 16815 dhcpd    CALL  unlink(0xbfbfd390)
 16815 dhcpd    NAMI  "/var/db/dhcpd.leases~"
 16815 dhcpd    RET   unlink 0
 16815 dhcpd    CALL  link(0x8077930,0xbfbfd390)
 16815 dhcpd    NAMI  "/var/db/dhcpd.leases"
 16815 dhcpd    NAMI  "/var/db/dhcpd.leases~"
 16815 dhcpd    RET   link 0
 16815 dhcpd    CALL  rename(0xbfbfd590,0x8077930)
 16815 dhcpd    NAMI  "/var/db/dhcpd.leases.962599316"
 16815 dhcpd    NAMI  "/var/db/dhcpd.leases"
 16815 dhcpd    RET   rename 0
 16815 dhcpd    CALL  socket(0x2,0x2,0x11)
 16815 dhcpd    RET   socket 5
 16815 dhcpd    CALL  ioctl(0x5,SIOCGIFCONF,0xbfbfb760)
 16815 dhcpd    RET   ioctl 0
 16815 dhcpd    CALL  ioctl(0x5,SIOCGIFFLAGS,0xbfbfb78c)
 16815 dhcpd    RET   ioctl 0
 16815 dhcpd    PSIG  SIGSEGV SIG_DFL
 16815 dhcpd    NAMI  "dhcpd.core"

I'll produce the entirety of the kdump if it's needed. It's just a bit
long.



>How-To-Repeat:

Update to netbsd-1-5, build dhcpd, and try to use it.

>Fix:

As yet unknown.
