I don't, at the moment. When I have time, I will build a gcc version with
bounds checking built in. For allocated memory, libary solutions may work very
well. For "normal" array, to me it seems, that compiler support for bounds
checking is best. Actually, I am puzzled, that compiler vendors don't do it.
Over ten years ago, I worked with Fortran under VMS. The DEC Fortran compiler
had a switch (VMS-language, if I recall correctly) /DEBUG=ALL, which included
bounds checking. With "modern" C-compilers, it seems not easily available. No
doubt, it might have very high costs at runtime. Many programmers won't care.

Regrads.
