[Discuss-gnuradio] Error while receiving

[kaleem ahmad]

Hi,

I am using USRP+RFX1400+SUSI

I am using following flow graph to receive data>

usrp_source_c -> gr.fir_filter_ccf -> gr.quadrature_demod_cf ->
gr.simple_correlator -> gr.vector_sink_b

Some time I receive following error:

*** glibc detected *** python: free(): invalid next size (fast): 0x08fcd970
***
Segmentation fault

Can you suggest what can be the problem and what can I do to solve it.

Thanks
Kaleem Ahmad
