That's a really weird backtrace - it seems to indicate that the
datatype engine is improperly calling free(). Can you try running
without openib (add "-mca btl_base_exclude openib" to the mpirun
arguments) and see if the problem goes away? Also, what platform was
this on?
Thanks,
Brian

I just committed a fix to the trunk to fix your original segfault

for
proper error handling/output.
The error below looks like a word size mismatch - one thing is
compiled
64bit, the other is compiled 32bit. Make sure everything is
compiled
either 32bit or 64bit.
Another note.. I think I may have had some problems because I
built with
'make -j16'.. has anyone else tried parallel make builds?
I have a working mpirun now.
Now I'm back to having NetPIPE segfault when I run it..
