If you are not using external32 in datatypes code, this issue doesn't matter. I don't think most implementations support external32...
Double free indicates application error. Such errors are possible but extremely rare inside of MPI libraries. The incidence of applications corrupting memory is about a million times higher than MPI libraries in my experience.
