AddCallback() for metrics (gauge) causes a `pure virtual method called` error

[Sowmya-Iyer]

The opentelemetry was built through CMake and imported as a cc_library with .so files into my Bazel environment.

• OpenTelemetry - v1.18.0
• Openssl - v3.0.15
• curl -v8.10.1
• abseil v20240116.1

Steps to reproduce

 void GaugeMetric::gauge_callback(metrics_api::ObserverResult result,
                                    void *state)
   {
      auto *instance = static_cast<GaugeMetric *>(state);
      if (opentelemetry::nostd::holds_alternative<opentelemetry::nostd::shared_ptr<metrics_api::ObserverResultT<double> > >(result))
      {
         auto observer_result = opentelemetry::nostd::get<opentelemetry::nostd::shared_ptr<metrics_api::ObserverResultT<double> > >(result);
         if (!instance->baggage.is_empty())
         {
            MaStr<Str> bag { { "test_baggage", "test_fixture" } };
            std::initializer_list<std::pair<opentelemetry::nostd::string_view, opentelemetry::common::AttributeValue> > attributes = {
               { "key1",     123 },
               { "key2",    45.6 },
               { "key3", "value" },
            };
            
            observer_result->Observe(instance->value.load(), bag);
            std::cout << "after" << std::endl;
         }
         else
         {
            observer_result->Observe(instance->value.load());
         }
      }
   }
void GaugeMetric::set_value(const double& val)
   {
      std::call_once(flag, [&]()
      {
         double_gauge->AddCallback(GaugeMetric::gauge_callback, this);
      });
      value.store(val);
   }

CleanUp code:

 auto meter_provider = dynamic_cast<metric_sdk::MeterProvider *>(metrics_api::Provider::GetMeterProvider().get());

      if (meter_provider)
      {
         meter_provider->ForceFlush();
         GB_DEBUG("Metrics force flushed.");
      }

While program termination, ForceFlush() is invoked which calls the Callback() function for GaueMetrics which ends in

pure virtual method called
terminate called without an active exception

Note: all my bazel tests pass, this is only an error occuring during program termination.

What is the expected behavior?
If the program does not add any baggage to Gauge Callback and uses only

            observer_result->Observe(instance->value.load());

the program terminates normally as expected. But adding baggage (map or std::initializer_list<std::pair<opentelemetry::nostd::string_view, opentelemetry::common::AttributeValue> > ) gives virtual method called error

@Sowmya-Iyer I think you used the api header file which is opentelemetry/api/metrics because in this header file you could find virtual functions and the error also says pure virtual method called, so the header file to use ObserverResultT is from the sdk which is opentelemetry/sdk/metrics/observer_result.h. Can you also please say which header file you used ? Thanks!

@Sowmya-Iyer
Did you remove the callback when your object lifetime ends?

void GaugeMetric::set_value(const double& val)
   {
      std::call_once(flag, [&]()
      {
         double_gauge->AddCallback(GaugeMetric::gauge_callback, this);
      });
      value.store(val);
   }

You didn't mention anything about RemoveCallback()
