Variable values before initialisaton
How could I go about looking into a fix? I wouldn't really know where
to start, but it is quite annoying for what am trying to do.
Thanks for your help.

You're extremely lucky you've int variables, and not C++ classes, and not
trying to call member functions of those.
The gdb/gcc combination has the bad habit of including not-yet-created
variables in the list of local variables. I don't think anybody's working
on a fix.
