[petsc-dev] valgrind errors in the SUPERLU*

The first leak is related to data structure for distributed sparse CSR
matrix A (input). How does the petsc interface free A's structure at the
end of program? There needs be a matching call like this:
Destroy_CompRowLoc_Matrix_dist(&A);
when A is not needed anymore.
I will go check all the MPI buffers.
By the way, I have a question about valgrind. Lately I have been chasing
a possible memory corruption on Cori at NERSC. Valgrind gave LOTS OF
internal system-related warnings, such as:
==39059== Conditional jump or move depends on uninitialised value(s)
==39059== at 0xD5E336: __register_atfork (register-atfork.c:119)
==39059== by 0xD5E418: __libc_pthread_init (libc_pthread_init.c:48)
==39059== by 0x6629E1: __pthread_initialize_minimal (nptl-init.c:462)
==39059== by 0xD14BDA: (below main) (libc-start.c:152)
==39059==
==39057== by 0xD5E418: __libc_pthread_init (libc_pthread_init.c:48)
==39057== by 0x6629E1: __pthread_initialize_minimal (nptl-init.c:462)
==39057== by 0xD14BDA: (below main) (libc-start.c:152)
This has nothing do do with my program. Do you know a way to NOT to print
those? I got a huge file filled with these, hard to find out the real
error.

> Another problem is that when running PETSc examples with Superlu we see

> filled with false positives).

> uninitialized data or better IMHO 2) send shorter messages that don't
> contain this part of the buffer that is never used anyway.
