    Description

      Link routing from router A through router B to a 'broker', and closing and opening two receivers causes a segfault.

      ==25674== Thread 4:

      ==25674==  If you believe this happened as a result of a stack
      ==25674==  overflow in your program's main thread (unlikely but
      ==25674==  possible), you can try to increase the size of the
      ==25674==  main thread stack using the --main-stacksize= flag.
      ==25674==  The main thread stack size used in this run was 8388608
      

      To reproduce, start three routers with the attached config files, then run the attached python test program.
