Andrew:

= =C2=A0Do you notice how much the image size will be increased when frame p= ointer is enabled?

I=E2=80=99d like to point out it is just not a m= akes working with the debugger better kind of feature as it is useful to pr= int out stack frames on ASSERT and exceptions.

For x86 you generally= unwind the stack until you hit a zero. It is probably also a good idea for= stack walker to skip guard pages, and non-canonical addresses so there is = probably some set of PCDs that would useful in this regards.
