Still getting this error message when trying to play with the new block
>>> gr_fir_ccf: using SSE
thread[thread-per-block[1]: <gr_block dd_mpsk_sync_cc (3)>]: gr_complex must be
8-byte aligned
I've pasted the py program code below - it's trivial. An initial offhand
diagnosis might suggest this is coming from somewhere in GR C++-land and isn't
caused by anything in the py source code...
