- ElectricFence, developed some years ago at Pixar corp. It's a malloc() heap
- debugger for UNIX. It places protected pages around your allocated blocks, so
- overruns can be caught using the usual segmentation violation mechanism.
- It has options to align the ends of blocks with the beginnings of pages, or
- vice versa. It can also optionally check for accesses to previously free()d
- space, by permanently marking such areas inaccessible (this can be a dog, for
- obvious reasons---expect to add virtual memory on the fly).
