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”

When I run for a sevral times digital_bert_tx.py with diffirent values

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

/usr/local/lib/libvolk.so.0.0.0
Can you help me please.
