Ok, I'm cc'ing discuss at mpich.org back.

Thanks.

Hmm.  The double free error seems to be coming from the executable, 
rather than from mpiexec or the proxy.  So we might be looking in the 
wrong place.

1. Can you run your application processes using "ddd" or some other 
debugger to see where the double free is coming from?  You might have to 
build mpich with --enable-g=dbg to get the debug symbols in.

2. Can you send me the output with the ssh launcher as well?  I want to 
see if there are any critical differences in the environment variables 
being propagated (e.g., LD_LIBRARY_PATH/LD_PRELOAD) that might affect 
shared library builds.

Feel free to send me the logs off-list.

Thanks,
