ABSTRACT:
A system for selective self-healing of memory errors comprises a processor coupled to a memory, where the memory stores instructions executable by the processor to store an error record for each memory management error detected during an execution of the application. The error record identifies an allocation location (e.g., a portion of a stack trace corresponding to the invocation of a memory allocation function such as malloc( )) of an object associated with the memory management error. The instructions are executable to use the error record to identify, during subsequent execution, memory operations performed on objects allocated from the allocation location, and to perform corresponding memory protection operations (e.g., operations to prevent re-occurrences of the memory errors) for the memory operations identified using the error record.
