[Discuss-gnuradio] gr_dd_mpsk_sync_cc: error - "gr_complex must be 8-byte aligned"

[ikjtel]

Trying to experiment with the new MPSK block now in git.  Getting the following 
error message - 

  thread[thread-per-block[10]: <gr_block dd_mpsk_sync_cc (34)>]: gr_complex 
must be 8-byte aligned

The ultimate source block in this case is a 
gr.file_source(gr.sizeof_gr_complex,...)

The python program was working using the older gr_mpsk_receiver_cc.  This is 
what happened when attempting to substitute the newer gr_dd_mpsk_sync...

Any ideas ?
