CLBlast: Unit tests and tuners segfault on Linux/Beignet with a Haswell GT2 GPU

I tried to run the test and they all fail the same way. They perform all sub-tests without errors, they report 100% pass rate then segfault:

CLBlast/build $ ./clblast_test_xswap -verbose true

* Options given/available:
    -platform 0 [=default]
    -device 0 [=default]
    -full_test [false]

    -cblas 0 [=default]
