Host Ubuntu 22.04.4 LTS

Reproduction steps:

sudo apt-get remove libbladerf-dev
git checkout https://github.com/Nuand/bladeRF.git
cd bladeRF/host
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Result: segfault when trying to use bladeRF-cli -l

sudo bladeRF-cli -l ~/hostedxA9-latest.rbf
Loading FPGA...
Segmentation fault

GDB shows the fault occurring here in bladerf2_load_fpga():

I can confirm I can compile and run sudo bladeRF-cli -l ~/hostedxA9-latest.rbf without a segfault from the 2023.02 tag. The current HEAD is 2fbae2c38b377cfbee98c281789cd43d1f1b55e4 at the time of writing.
