Hello,

Just following up on this from a few weeks ago since no one seems to
have responded. Does anyone have any suggestions as to whether this is
a genuine memory leak with OpenMPI or some other kind of problem I
need to debug?

For more real-world context: this was triggered by a CFD code we use
in our research group, which uses the Boost MPI library. As part of
its serialization of std::vectors, Boost makes use of MPI_Alloc_mem
(balanced by MPI_Free_mem, as in the example I gave), and this appears
to be the cause of a memory leak which eventually results in some of
our simulations crashing due to lack of memory. So, there's no obvious
way I can work around this without replacing a lot of Boost code by a
hand-coded equivalent.

Any suggestions welcome.

Thanks,

Philip
