[srslte-users] Segmentation Fault for srsUE tests

[jan acosta]

Hello,

I am getting a segmentation Fault for the ue_itf_test_sib1,
ue_itf_test_prach, and mac_test.  They all have very similar outputs as
below.  I'm not sure what the problem is.  Below is the gdb backtrace.

I'm using a B210 and when I ran benchmark_rate from uhd I am getting a
steady  30 MHz IO.

Please take a look.  Thanks.
