Description ac131313 2002-04-17 15:18:01 UTC 
[Converted from Gnats 497]

(Given GDB currently isn't very good at debugging optomized code, the probably of seeing this is very low - you need a frameless non-leaf function.)

To correctly identify a frame both the ``frame addr'' and the ``frame func'' are needed.  The ``frame func'' is used to break the case where two frames have the same ``frame addr''.

The command -var-create only takes a frame.  This means that it currently can't always correctly identify the current frame.

The command should be extended (option?) to also take the function (of course this requires the corresponding print frame code to print a addr/func pair when displaying frames.

Release:

 Update.
 
 GDB now has a frame ID and that contains both the frame and the func.

Sounds like this was fixed 20 years ago.
