It's the bleeding edge of 3.7.12.

But you're not running the test in gr-zeromq - you're running the test
in gr-fec.

gr-zeromq has it own tests which don't depend on gsl.

The fact it can't run the sub test qa_zeromq_sub is an artifact of not
being able to run *ANY* of the tests in gr-fec with gsl-2.x.

In short, nothing has changed.

False.

It just didn't print a Failed message - presumably a race condition -
which is not the same as Passed.

If 1 one tests passed , it would indicate the number tests which Passed
and the number of tests which Failed.

It's failing all the tests - it can't complete a single test.

But it is repeatable - it fails everything every time.
