Tracer.WithActiveSpan RedHat Entreprise Linux 9.4

Problem
I am encountering a test failure with Tracer.WithActiveSpan and unsure what might be causing this. The test expects the spas trace id and the first space context trace id to mismatch. However mine match. Any ideas?

EXPECT_NE(spans.at(0).get()->GetTraceId(), span_first->GetContext().trace_id());

Bonjour @olivier-perrault-ibm

I am very puzzled by this part of the test failure:

/home/fyreuser/repos/ace-tracing/opentelemetry-cpp/sdk/test/trace/tracer_test.cc:1076: Failure
Expected: (spans.at(0).get()->GetTraceId()) != (span_first->GetContext().trace_id()), actual: 16-byte object <8E-23 D2-6D B7-9B 1E-4B 14-C8 87-1B 2D-DE CE-32> vs 16-byte object <8E-23 D2-6D B7-9B 1E-4B 14-C8 87-1B 2D-DE CE-32>

According to this test log, the test fails because the two parts are expected to be different, and yet they are equal (and the binary bumps are identical).

In the opentelemetry-cpp source code, the line that corresponds to opentelemetry-cpp/sdk/test/trace/tracer_test.cc:1076 reads as:

    EXPECT_EQ(spans.at(0).get()->GetTraceId(), span_first->GetContext().trace_id());

This is EXPECT_EQ, which expects ... equality.

Please clarify the exact version used for opentelemetry-cpp, down to the github commit or label, and clarify if you have any local changes.

Also, please clarify if other tests are also failing and how, this will help to identify the root cause.

Thanks.
