I'd possibly actually prefer debug builds to initialise with some value like 0x7777777777777777, which is very unlikely to be a valid pointer even with some arithmetic and is also likely to give obviously-wrong errors when used as arithmetic.  The problem with 0 is that 0 quite often is a valid, but wrong, value.
