gpart: Invalid argument

after recreate ada0s1 there gpart shows 4 GEOMs with BSD partitioning
(numbers are same as above):
ada0s1
ada0s1
ada0s1c
ada0s1c


----------------------
If I create BSD scheme with old good bsdlabel(8): (numbers are written
by hands to minimize reboot count)
#gpart delete -i 1 ada0s1
#gpart delete -i 2 ada0s1
#gpart destroy ada0s1
#bsdlabel -w ada0s1
#gpart show ada0s1
=> 0 411807627 ada0s1 BSD (196G)
  0 16 -free - (8.0k)                                     ---> used by
BSDLabel data
 16 411807611 1 !0 (196G)                          ---> ada0s1a

and this label is correct.

I think that GEOM part create and add commands must add some gap
before partitions for any schemes and bug is here.
