Walter,
can the gc's method of detecting a pointer to object be used to allow debug
code to detect the array that a pointer is pointing into and so allow
pointer to also be bounds checked (debug only as I assume it will be an
expensive operation) ?

Potentially, yes, although the gc allocates more memory that is required by
the array, so this check would still let slip through invalid pointer
offsets.
