When I run RXE Test plan, ibv_*_pingpong has no problem, but udaddy server got Segmentation fault.

[root@localhost examples]# udaddy -s 192.168.77.149
udaddy: starting client
udaddy: connecting

[root@localhost examples]# udaddy

Then I use gdb, the error is as follows.
Program received signal SIGSEGV, Segmentation fault.
