Hi guys,

everyone has same issue:

Created default thread pool with 8 threads.
>>> gr_fir_fff: using SSE
swig/python detected a memory leak of type 'gr::basic_block_sptr *', no destructor found.
Traceback (most recent call last):
File "/home/aero/top_block.py", line 77, in <module>
tb = top_block()
File "/home/aero/top_block.py", line 63, in __init__
self.connect((self.digital_gmsk_mod_0, 0), (self.osmosdr_sink_0, 0))
File "/usr/local/lib/python2.7/dist-packages/gras/GRAS_PyHierBlocks.py", line 171, in connect

File "/usr/local/lib/python2.7/dist-packages/gras/GRAS_PyHierBlocks.py", line 162, in internal_connect__
sink = to_element(sink)
File "/usr/local/lib/python2.7/dist-packages/gras/GRAS_PyHierBlocks.py", line 145, in to_element
except: raise Exception('cant coerce obj %s to element'%(obj))
Exception: cant coerce obj <gr_block sink_impl (0)> to element

?

Very simple flow graph File Source -> Packet Encoder -> GMSK mod -> osmocom sink (bladerf)
