I am currently debugging a very large program in Ubuntu 16.04 LTS which uses OpenMPI and have encountered some memory leaks. Using Valgrind, the error seems to be stemming from main (main.c:13) (which is not part of the program), ORTE and OPAL which are sub packages of OpenMPI.
The question is whether this is a bug in the program or OpenMPI itself and whether this only occurs for some MPI method or MPI datatype.
Below is the output from Valgrind using the -g -O0 -fno-inline C++ compiler flags and --tool=memcheck --leak-check=yes --track-origins=yes --leak-check=full valgrind flags.
