Isn't the solution as easy as doing:
OR PTR:[address], 0
the same way it's done for the stack?

The offset it known at compile time in most cases, so the command 
would be required only if both:
* The object is larger than target OS' guard page size.
* The position is greater than target OS' guard page size, OR is 
unknown at compile time.
