The pop command removes one or more frames from the call stack. It is valid only in native mode.
You can pop only to a frame for a function that was compiled with -g. The program counter is reset to the beginning of the source line at the callsite. You cannot pop past a function call made by the debugger; use pop -c.
Normally a pop command calls all the C++ destructors associated with the popped frames; you can override this behavior by setting the dbx pop_auto_destruct environment variable to off (see Setting dbx Environment Variables).
Pop current top frame from stack.
Pop number frames from stack.
Pop frames from stack until specified frame number.
Pop the last call made from the debugger.
number is the number of frames to pop from the stack.
