problem solved adding:

binaryErode->SetBackgroundValue( 0 );
binaryErode->SetForegroundValue( 255 );

to

hope it helps someone else: this thing was undocumented.
It is incredibly slow, but probably switching to ITK 3.4 will solve the problem.
By the way, do you have any idea how to update just the
erosion/dilation from 3.2 to 3.4 without reinstalling everything (it
needs time, I want to postpone this)
