[mpich-discuss] error :Assertion failed in file ch3u_buffer.c at line 77: 0 memcpy argument memory ranges overlap

[Dave Goodell]

What version of MPICH2 are you using?

Are you configuring with "--with-device=ch3:nemesis:mx"?

It looks like you are doing a send/recv to/from the same process with the same buffer. It's OK to send/recv to/from the same process, but you must use distinct buffers.
