"These patches add a -fbounds-checking flag that adds bounds checking tests to pointer and array accesses. Richard Jones developed the patches against gcc 2.7 in 1995. Herman ten Brugge is the current maintainer and has updated the patches for GCC 2.95.2 and later. William Bader has patches as well.

You may freely mix object modules compiled with and without bounds checking. The bounds checker also includes replacements for mem* and str* routines and can detect invalid calls against checked memory objects, even from modules compiled without bounds checking."

"The emx port of GCC includes Richard W.M. Jones's bounds checking patches. See the GCC manual and \emx\gnu\doc\bounds\README for details."

"SAFE! tcc includes an optional memory and bound checker. Bound checked code can be mixed freely with standard code."
