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.
