Description
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());

Research direction
The failure is in sdk/test/trace/tracer_test.cc at lines 1075-1076, in Tracer.WithActiveSpan; start by running that GoogleTest case and comparing the reported parent and trace IDs. Reproduce it on Red Hat Enterprise Linux 9.4, then trace the implementation used by the test to determine why its expectations differ. Completion requires identifying the cause and documenting the appropriate resolution.
