A couple of things. First, in the make function, you want to return:
return gnuradio::get_initial_sptr (new gr_my_divisorcamadas_ff ());
This is to make sure the pointers are cleaned up properly upon closing the
program.
More importantly, you don't have a destructor defined. You have it in the
header file but no actual code for it. I'm surprised you're not getting a
compiler error about this. Might be your problem.
