Segmentation fault error on send-performance program

[ft-ksc]

Hi,

When I run send-performance program on two RDMA-connected Ubuntu machines, I get the "Segmentation fault" error.
I tried running rping on the machines and it worked. However, read-write-send and send-performance programs outputs "Segmentation fault" error.

Could you please inform me why this happens and recommend ways to solve this issue?

Best regards.
