I highly suspect that your "dados" parameter is wrong, either it is not 
allocated, or you are passing the wrong pointer in there, that's why you are 
getting your error. Try adding this line after your printf:

printf("   - dados = %p, dados->i = %ld\n", dados, (long int)dados->i);

I guess that the segmentation fault will happen also on this line, showing that 
"dados" is incorrect.
