--annotate=3  & --fullpath are _SORT_ of incompatible.
If you invoke GDB with both the options (i.e fullpath and annot =3)
the annotation level is _SILENTLY_ set to 1, you can check this by
trying "gdb> show annotation". With the annotation set to 1 (albeit
silently) your local,stack etc window cannot be displayed.My advice
would be try giving up the need to specify --fullpath along with
annotation=3, read up on GDB/M1 and experiment :)

Just do away with the need of specifying --fullpath and let
annotation=3 as is.
