Comment #4 on issue 825 by [email protected]: LiveEdit: stack
manipulation does not work with function without local variables
http://code.google.com/p/v8/issues/detail?id=825
The issue problem technical description.
LiveEdit has to restart a single function on top of the stack. The function
stack frame is to be replaced with a temporary "Frame Dropper" frame.
According to V8 stack format, JavaScript frame has a minimum size of 4
words, but internal frame has a minimum size of 5 words. This makes
possible a title case when JavaScript function without local variables
occupies only 5 words on stack that makes us unable to fit "Frame Dropper"
frame in its place.
