[tcpprep] Auto/Router mode test: /bin/bash: line 1: 2371998 Bus error ../src/tcpprep --no-arg-comment --dbug=1 -i ./test.pcap -o test.auto_router1 -a router >> test.log 2>&1
make[2]: *** [Makefile:690: auto_router] Error 135
On my local boxes, I can confirm this behaviour.

So I'd ask you to re-visit this issue and find a better solution for it.
Reverting that commit doesn't look like a good idea, and also introduces another issue, I haven't checked further:
