Jeff and Nathan,
Thank you for your replies; the leak doesn't happen with MPICH 3.2.1,
so it's probably OpenMPI specific. I've opened
https://github.com/open-mpi/ompi/issues/4567 I don't seem to be able
to assign the issue but I've tagged Nathan in the comments.
Kind regards,
Philip

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
Hello,
I appear to have found a memory leak in OpenMPI, using the following
simple program (memory_leak_check_minimal.C):
#include
int main(void)
{
int i=0;
MPI_Init(&i, NULL);
char* result;
for(size_t i=0 ; i < 1 ; i++)
{
MPI_Alloc_mem(100, MPI_INFO_NULL, &result);
MPI_F
