The problem is that the variable is only referenced inside an assert(), which is presumably being compiled out under RelWithDebInfo.

I'd just add a (void)ret; after each of those lines.

Call rcutils_logging_shutdown() in TearDown
to avoid leaking logging internal objects.

As any change to this file makes test_logging_named
fail, this releaxes the EXACT_EQ call on
g_last_log_event.location->line_number[1]. Instead
of looking for a particular value, we test an invariant
of the field (line numbers are positive).

Finally, in test_logging_function, initialize g_counter
and g_function_called values to make sure the test will
not fail even if `--gtest_repeat=2` is passed.

Other tests are still failing when this flag is passed:
[  FAILED  ] TestLoggingMacros.test_logging_once
[  FAILED  ] TestLoggingMacros.test_logging_skipfirst
[  FAILED  ] TestLoggingMacros.test_logging_skipfirst_throttle

However, fixing those tests would require actually changing
the logging implementation which is out of the scope of this
change.
