PetscMallocClear

 Resets the routines used to do mallocs and frees to the defaults.

Synopsis

#include "petscsys.h"   
PetscErrorCode PetscMallocClear(void)
Not Collective

Notes

In general one should never run a PETSc program with different malloc() and free() settings for different parts; this is because one NEVER wants to free() an address that was malloced by a different memory management system

Called in PetscFinalize() so that if PetscInitialize() is called again it starts with a fresh slate of allocation information
