[RFC] breakpoints and function prologues...

We're talking Mac here right?  I thought (sarcasm) Mac users did 
everything using the GUI and AppleScript.

Is your [apple] bug with a GUI user finding that a breakpoint on a 
function confuses the GUI; or with a GUI user finding that entering the 
CLI command ``break file.c:10'' confuses the GUI?  (A CLI user would 
have used ``break func'' :-)

We've concluded that the former can be fixed without any need to change 
the CLI.

For the latter, the user can still enter ``break *0x1234'' and confuse 
the GUI.  Should GDB ``helpfully'' move that as well?  I think the only 
thing that can be done is ensure that the GUI doesn't get confused (or 
at least gets confused gracefully :-).  For instance, realise that its 
got a PC in the prologue and display ``incomplete stack frame''.
