Here is the ouput of your DTrace script:
# dtrace -n ldi_get_size:return'{trace(arg1)}'
dtrace: description 'ldi_get_size:return' matched 1 probe
CPU ID FUNCTION:NAME
1 24930 ldi_get_size:return -1
With the command:
# zpool create tank /dev/dsk/vpath1c
warning: device in use checking failed: No such device
internal error: unexpected error 22 at line 446 of ../common/libzfs_pool.c
