CHKMEMQ
Checks the memory for corruption, calls error handler if any is detected
Synopsis
#include <petscsys.h>
CHKMEMQ;
Not Collective
Notes
We highly recommend using valgrind http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind for finding memory problems. This is useful
on systems that do not have valgrind, but much much less useful.
Must run with the option -malloc_debug to enable this option
Once the error handler is called the calling function is then returned from with the given error code.
By defaults prints location where memory that is corrupted was allocated.
Use CHKMEMA for functions that return void
