Hello All,
I have a Segmentation fault (core dumped), when i run

./digital_bert_rx.py -f 2460M --rx-gain=30 --args=“addr=192.168.10.2”
./digital_bert_tx.py -f 2460M --tx-gain=30 --args=“addr=192.168.10.3”
–amplitude=0.2
When I run for a sevral times digital_bert_tx.py with diffirent values
of amplitude this error apear, like in this capture.

I tried to debug the error and I found that the error was comming from a
gnuradio kernel. The segmentation error is from this file :
volk_32fc_32f_dot_prod_32fc.h
Program received signal SIGSEGV, Segmentation fault.[Switching to Thread
0x7f6cdaffd700 (LWP 5423)]0x00007f6cf51d2e87 in
volk_32fc_32f_dot_prod_32fc_a_sse () from
/usr/local/lib/libvolk.so.0.0.0

Can you help me please.

Hi Raf,

Can you provide more details? How did you install GNU Radio and what
hardware are you running on? When you start the application you should
see a message along the lines of “Using VOLK machine: xxxx”. What are
the xxxx’s?
