[mpich-discuss] Assertion failed in file src/mpid/ch3/src/ch3u_handle_send_req.c at line 61 (RMA && Derived datatypes)

[Balaji, Pavan]

Victor,

We believe this has been fixed in mpich/master.  Please download the latest mpich nightly snapshot and give it a try to see if it fixes the issue for you.

FYI, the mpich website is down for maintenance at the moment.  It should be back up in a couple of hours (or sooner).

The GCC v4.7.3 and Intel v15.0.0 were used to compile MPICH v3.1.3 on my laptop and on HP SL203S, respectively. Moreover, the  MPICH v3.1.3 used includes the '920661c3931' commit by Xin Zhao.
