Ok, fair enough.

Hi Kjell-Arne,
The released installed is configured only with Intel Fortran compiler,
it won't work with other Fortran compilers. If you want to stick with
GNU compilers, you probably could try GNU f77 or g95. But anyway, the
MinGW build is only experimental, there still might be runtime issue
Hi Toufik,
I'm not 100% sure about this. Could you provide a small example that I
can test on? Thanks.

Many thanks for trans-coding to C; this was a major help in debugging the issue.
Thankfully, it turned out to be a simple bug. OMPI's parameter checking for
MPI_ALLGATHERV was using the *local* group size when checking the recvcounts
parameter, where it really should have been using the *remote

It seems like this might also be an issue for gatherv and reduce_scatter
as well.

Gah. I spot-checked a few of these before my first commit, but didn't see
these.
So I checked them all, and I found SCATTERV, GATHERV, and REDUCE_SCATTER a

I forgot to mention -- this issue exists waaay back in the Open MPI code base.
I spot-checked Open MP
This bug had the opportunity to appear in all collectives supporting
intercommunicators where we check the receive buffer(s) consistency. In
addition to what Jeff fixed already, I fix it in ALLTOALLV, ALLTOALLW and
GATHER.

FWIW, the nightly tarballs of the head of the v1.6 SVN branch are available
here:
http://www.open-mpi.org/nightly/v1.6/
There's only been a few minor fixes applied so far after 1.6 was released:
