The "error *** glibc detected *** $(PROGRAM): double free or corruption" is ubiquitous and rarely has anything to do with MPI. As Gilles said, use a debugger to figure out why your application is corrupting the heap. Jeff On Wed, Jun 14, 2017 at 3:31 AM, ashwin .D

Hi, at first, i suggest you decide which Open MPI version you want to use. the most up to date versions are 2.0.3 and 2.1.1 then please provide all the info Jeff previously requested. ideally, you would write a simple and standalone program that exhibits the issue, so we can reproduce and

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
