nope, that makes no sense. There is no allocated area when you ask for
zero bytes. You can't stick values before or after an area that
Jerry did the right thing in his commit.
btw, if what you want is guard regions around all non-zero sized
allocs then that is normally a good idea, but doesn't actually work
for talloc(). In a normal alloc there is a free() fn, and the free fn
can check the guard areas and give a warning if they are corrupted. In
the case of talloc there is no free fn so the guard areas would be
