PetscMallocValidate

Test the memory for corruption. This can be called at any time between PetscInitialize() and PetscFinalize()

#include "petscsys.h" 
PetscErrorCode  PetscMallocValidate(int line,const char function[],const char file[])

	line	- line number where call originated.
	function	- name of function calling
	file	- file where function is

The number of errors detected.

Options Database:.

	-malloc_test	- turns this feature on when PETSc was not configured with --with-debugging=0
	-malloc_debug	- turns this feature on anytime

Error messages are written to stdout.

This is only run if PetscMallocSetDebug() has been called which is set by -malloc_test (if debugging is turned on) or -malloc_debug (any time)

You should generally use CHKMEMQ as a short cut for calling this routine.

The Fortran calling sequence is simply PetscMallocValidate(ierr)

No output is generated if there are no problems detected.

Uses the flg TRdebugLevel (set as the first argument to PetscMallocSetDebug()) to determine if it should run
