[Discuss-gnuradio] understanding decimator block

[BHN66]

hello everyone,

i'm trying to understand a decimator block and how to write such a block by myself. for testing and learning purposes only i have written a simple block. the c++-code you can see in "cpp_code.png" and the python qa-code you can see in "qa_python.png". there is an input vector (1,4,3,9,5,2,4,1,6) and it should calculate the sum of every three numbers (1+4+3=8, 9+5+2=16, ...)

everytime i get a segmentation fault error message. do anybody know why?

 

thanks for your help!
