[j-nsp] rpd crash JUNOS 7.4R1.7

[Jeff S Wheeler]

The following configuration(s) on JUNOS 7.4R1.7 cause rpd to crash.  A
rollback is necessary, or rpd will continue to restart and immediately
crash again.  I have changed the IP/AS numbers to conform to my NDA.  I
do not have the necessary lab resources to reproduce this outside of my
client's production network.

I believe this is probably an unusual configuration, and may not be
intended to work; but if so it should fail `commit check` with error
messages or perhaps silently ignore the as-path alternations, rather
than allow the box to be configured in an unstable manner.
