I am attempting to test a block that takes in complex samples and outputs PMT objects. In order to properly test it, I need to run a vector through it and verify that the correct number of PMT objects were created. Thus far I have not run across any blocks that act like a vector sink for PMT objects. So, I created my own in Python. When I run with the custom PMT sink the graph never stops. If I create the same PMT sink in C++ then everything works as expected. Attached is some example code. If you build gr-poopie with `cmake .. && make && sudo make install && sudo ldconfig` you can then run the `test.py` script in the base directory. It should work for the first three tests and then hang on the last one.
Thanks!
