PETSc version 3.15.5
PetscMallocDump
Dumps the currently allocated memory blocks to a file. The information printed is: size of space (in bytes), address of space, id of space, file in which space was allocated, and line number at which it was allocated. 
Synopsis
#include "petscsys.h" 
PetscErrorCode  PetscMallocDump(FILE *fp)
Not Collective
Input Parameter
|  | fp | - file pointer.  If fp is NULL, stdout is assumed. | 
Options Database Key
|  | -malloc_dump <optional filename> | - Dumps unfreed memory during call to PetscFinalize() | 
Fortran Note
The calling sequence in Fortran is PetscMallocDump(integer ierr)
The fp defaults to stdout.
Notes
Uses MPI_COMM_WORLD to display rank, because this may be called in PetscFinalize() after PETSC_COMM_WORLD has been freed.
When called in PetscFinalize() dumps only the allocations that have not been properly freed
PetscMallocView() prints a list of all memory ever allocated
