Review comment:
I'm running a Debug build. This error does not happen on every run. Also,
I'm seeing an occasional failure with an assert link_route_proxy.c#371, a lrp
pointer points to a proxy with bad proxy_state.
Attached are two files that have the grinder result from two runs only of
system_tests_edge_router.
- grinder-at-1246.txt has the bad memory reference and the assert.
- grinder-at-1246-2.txt has no bad reference, no assert, and a varying set
of object leaks.
