I've never seen it.

It appears to be part of the new local label prefix filter feature of
some sort.

ie:

76k-123-3#config t
Enter configuration commands, one per line.  End with CNTL/Z.
76k-123-3(config)#ip prefix
76k-123-3(config)#ip prefix-list p0 permit 1.1.1.1/32
76k-123-3(config)#ip prefix-list p0 permit 1.1.1.2/32
76k-123-3(config)#end                                
76k-123-3#config t         
76k-123-3(config)#mpls ldp label 
76k-123-3(config-ldp-lbl)#allocate ?
  global  Specify global Routing/Forwarding instance

76k-123-3(config-ldp-lbl)#allocate global ?
  host-routes  allocate local label for host routes only
  prefix-list  Specify a prefix list for local label filtering
  

76k-123-3(config-ldp-lbl)#allocate global prefix-list p0 
76k-123-3(config-ldp-lbl)#end

76k-123-3#
76k-123-3#sh ip prefix
ip prefix-list p0: 2 entries
   seq 5 permit 1.1.1.1/32
   seq 10 permit 1.1.1.2/32


76k-123-3#config t
Enter configuration commands, one per line.  End with CNTL/Z.
76k-123-3(config)#no mpls ldp label 
76k-123-3(config)#end
76k-123-3#sh ip prefix
ip prefix-list p0: 2 entries
   seq 5 permit 1.1.1.1/32
   seq 10 permit 1.1.1.2/32
ip prefix-list p2: 1 entries
   seq 5 permit 18.18.18.18/32
ip prefix-list p4: 1 entries
   seq 5 deny 0.0.0.0/0
ip prefix-list p9: 1 entries
   seq 5 deny 0.0.0.0/0 le 1
76k-123-3#config t
Enter configuration commands, one per line.  End with CNTL/Z.
76k-123-3(config)#no ip prefix-list p0
76k-123-3(config)#end
76k-123-3#sh ip prefix-list 
.....

crash


It's fixed in 12.0S branch but hasn't been picked up anywhere later.
