CheckPointer - A C Memory Access Validator

Abstract

Check Pointer is a memory access validator for checking spatial and temporal pointer usage errors in multi-threaded applications by tracking meta data and validating pointer dereferences at run-time. The tool uses source-to source transformations implemented with DMS to instrument the source code of the application to be validated with meta data checks. Libraries available only in binary form are handled by using function wrappers that check meta data immediately before calling a library function and update meta data as necessary immediately after the library function returns.
