IIRC that is mixing up 2 things. But in Graeme favour, likelihood has 
it, that others have mixed it up before: so this may have been said the 
way quoted (but not necessarily by people people listed)

IIRC there are several technical underlying issues (but I may be wrong): 
like not yet implemented to call functions from the debugger at all; and 
issues to represent the same symbol as getter and setter with the means 
of stabs/dwarf ?

The "accidental change" is more an argument, to have the function off by 

And true, no one ever complains about having had that problem. Those who 
do have it are often beginners, they have no idea what it is, they blame
