Description daveg 2000-10-23 17:30:00 UTC 
The rn_mklist field of the radix_node structure is not always set to 
NULL when a radix_node is inserted into the radix tree.  This can 
cause the code to incorrectly traverse a rn_mklist list and also
causes rn_delete() to emit log messages.

Fix: zero out the rn_mklist field in the function rn_newpair().

*** radix.c     2000/05/25 17:14:47     1.2
--- radix.c     2000/10/16 17:29:25     1.3
***************
How-To-Repeat: Continual add and remove radix_node from a radix tree.
