[mpich-discuss] question about valgrind errors I am getting

[Grindeanu, Iulian R.]

hello,
I am trying to see where is the leak in our code;
valgrind shows some leaks, like these

==4262== 1,512 bytes in 3 blocks are still reachable in loss record 6 of 6
==4262==    at 0x4C2CC70: calloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==4262==    by 0x56A6555: set_collops.part.0 (in /home/iulian/3rdparty/mpich-3.1/install/lib/libmpich.so.12.0.0)
==4262==    by 0x56A73E2: MPIR_Comm_commit (in /home/iulian/3rdparty/mpich-3.1/install/lib/libmpich.so.12.0.0)
==4262==    by 0x56DFAD3: MPID_Init (in /home/iulian/3rdparty/mpich-3.1/install/lib/libmpich.so.12.0.0)
==4262==    by 0x5796878: MPIR_Init_thread (in /home/iulian/3rdparty/mpich-3.1/install/lib/libmpich.so.12.0.0)
==4262==    by 0x5796288: PMPI_Init (in /home/iulian/3rdparty/mpich-3.1/install/lib/libmpich.so.12.0.0)
==4262==    by 0x40B20B: main (read_nc.cpp:18)


in our code, line 18 is MPI_Init(..)

commenting out portions of our code gets rid of the leaks; 
do you have a suggestion what are we doing wrong, or what is the leak related to? Or  could it be a false positive from valgrind?


Thanks,
Iulian
