Memory error detection (new series)

Just before I left Oracle I sat down with my good friend Raj and we wrote up a bundle of stuff on Memory Error Detection. He's started posting it on his blog.

Memory errors are one of the common types of application error - accessing past the end of arrays, or past the end of a block of allocated memory, reading memory that has not yet been initialised, and so on. What makes them particularly nasty is that they are hard to detect, and the effect of the memory access error can be arbitrarily far from the place where the error occurs. So it's useful to have tools which help you find them.....
