Well, this is where it gets tricky.
Answering question (2) first, I'd say it is not widget at all, since we
can pretty safely assume that no widgets will have been allocated with
an address as low as 0x3...
It is most likely that you have a widget pointer somewhere that is
either entirley un-initialised, or which has been over-written with the
value 3 for some reason.
I'd tend towards the "accidental over-writing with 3 option", and fish
about in the code to see where that might happen.
Un-initilaised pointers tend to be either 0 (if they have static scope)
or some random value (if they are stack automatic.)
However, if you are creating widgets on the stack, and something else on
the stack previoulsy was a 3, then...
Are you creating widgets on the stack? If so, try making them static
instead to see if your segfualt suddenly becomes a 0x0 rather than an
0x3 !
