The comment says:

    	/*
    	 * Use the execution context in the current selection as the input provider.
    	 * This insures that the REGISTER VIEW will not collapse and expand on stepping or on
    	 * re-selection in the DEBUG VIEW.  Currently the register content is not stack frame
    	 * specific. If it were to become so then we would need to modify this policy.
    	 */

I've been trying things out with GDB and it seems that register content _is_ stack
frame specific.  When I change frames in GDB and ask for register content, I get a different
set of content depending on the stack frame that I selected.  This makes particular sense
for registers like stack pointer, instruction pointers, but the others too.

CDI does not have this problem.

Seems like a bug to me.  And a pretty old one at that.

Can you open a bug?

Thank you

Marc

What do you mean by "CLI usage"?
