<div>abort trap: 6</div></div><div><br></div><div>I&#39;ve attached a short test program that just makes 2 isend calls and 2 irecv calls from rank 0 to rank 0, sleeps briefly, then tries to test the irecv requests.</div><div>
<br></div><div>Interestingly, the test succeeds if only one call is made or if a native MPI type is used.  That is, I only get the failure with multiple asynchronous requests of serialized types.</div><div><br></div><div>
I&#39;ve tried the test on a Mac with boost 1.55 and OpenMPI 1.73, and on Debian Wheezy with boost 1.49 and OpenMPI 1.45. I see the same basic error on both.</div><div><br></div><div>Is this something that should work that I&#39;m just doing incorrectly? Or am I trying to do something that isn&#39;t supported?</div>
