Bounds Checking
Bounds checking is a compiler-based technique that adds run-time bounds information for each allocated block of memory, and checks all pointers against those at run-time. For C and C++, bounds checking can be performed at pointer calculation time or at dereference time.
Implementations of this approach use either a central repository, which describes each allocated block of memory, or fat pointers, which contain both the pointer and additional data, describing the region that they point to.

Famous quotes containing the word bounds:
“Great Wits are sure to Madness near alli’d
And thin Partitions do their Bounds divide;
Else, why should he, with Wealth and Honour blest,
Refuse his Age the needful hours of Rest?”
—John Dryden (1631–1700)
