ABSTRACT:
A method of identifying the source of a memory corruption error during operation of a checkpoint library includes receiving an error detection request and, in response to the request, write protecting all memory regions allocated to a checkpoint library. The method further includes detecting when a memory region is accessed for modification during operation of the checkpoint library and, in response to the detection, identifying the source of a memory corruption error affecting the memory region.
