[Discuss-gnuradio] Fwd: Random test failures when compiling GNURadio from source

[Kevin George]

Hello,

We have been trying to compile and run GNURadio from source and the make tests have been failing randomly.

Machine Details

Intel NUC (x86-64 machine)

Ubuntu 16.04.03

GNU Radio version 3.7.11

gcc version 5.4.0 20160609

Commands used

git clone --recursive https://github.com/gnuradio/gnuradio

git checkout v3.7.11

mkdir build

cd build

cmake -DENABLE_GR_QTGUI=OFF -DCMAKE_INSTALL_PREFIX=/usr/local ../

make -j4

make test

Out of every 4 compilations, 1/2 would fail the make test e.g qa_constellation_receiver(attached error with email) or
qa_ofdm_sync_sc_cfb. Our fix so far has been to re-run the build with no modifications and the tests pass.

I have seen similar errors pop up in the mailing lists and the cause is usually incorrect setting of seed.
e.g https://lists.gnu.org/archive/html/discuss-gnuradio/2012-04/msg00318.html

Does this issue still persist? or known?

Kevin
