Building gnuradio/master on Windows XP with MSVC++ 2010, I find that the
test example qa_constellation_receiver_test hangs. Setting
in gr_block_executor.cc shows that gr_clock_sync_ccf’s general_work() is
being called repeatedly with noutput_items=1. But said general_work()
produces output for i < noutput_items-d_osps, so it produces no output
noutput_items and d_osps are both equal to 1.
This behavior occurs after the vector_source and all preceeding block
Not knowing exactly what gr_clock_sync_ccf is supposed to do and how it
supposed to work, I am having trouble debugging the problem further.
