what i checked is a small application called udaddy which is part of the librdmacm examples. But this information I think is useless since the method which actually reveled this issue is part of my own built private version of libibverbs. however I'm intend to write you a small app to demonstrate this faulty behavior - it actually should should be almost the same as the code snippet + some setup routines.
