Hitting issue of large alloc which crashes application

[yzhuang93]

Recently bumped up our OTEL CPP client version to 1.16.1 and also use STL instead of ABSEIL, but hit into this issue at run time:

tcmalloc: large alloc 139896905007104 bytes == (nil) @  0x7f3c4a43154c 0x7f3c426154b0 0x7f3c492c6db3 0x7f3c490c5dd4 0x7f3c48bb44b6 0x7f3c495180c8 0x7f3c49517616 0x7f3c4a30ab2e 0x7f3c4a302825 0x7f3c4a306295 0x7f3c41e6c7e5

The line of code hitting this issue is
tracer_ = trace::Provider::GetTracerProvider()->GetTracer("otel", "1.16.1");
If I change back to use abseil then I don't see this issue, but I have some other problem of using abseil and need to get rid of it.

Adding some more info about the code

  // Create exporter with [OtlpHttp]ExporterFactory.
  otlp::OtlpHttpExporterOptions opts;
  opts.url = config_->ExporterEndpoint();
  auto exporter  = otlp::OtlpHttpExporterFactory::Create(opts);

  // Create Batch Span Processor with [Batch]SpanProcessorFactory.
  sdktrace::BatchSpanProcessorOptions processor_option{};
  auto processor = sdktrace::BatchSpanProcessorFactory::Create(move(exporter),
    processor_option);

  // Create Sampler with [AlwaysOn]SamplerFactory.
  auto sampler = sdktrace::AlwaysOnSamplerFactory::Create();

  // Create Resource with info service_name, hostname and ip.
  auto resource = sdkresource::Resource::Create({
    {"service.name", service_name_},
    {"hostname", hostname_},
    {"ip", ip_address_}
  });

  // Create ID Generator with [Random]IdGeneratorFactory.
  auto id_generator = sdktrace::RandomIdGeneratorFactory::Create();

  // Create Tracer Provider with TracerProviderFactory.
  shared_ptr<sdktrace::TracerProvider> tracer_provider
    = sdktrace::TracerProviderFactory::Create(
        move(processor), resource,
        move(sampler), move(id_generator));

  // Set global tracer provider.
  shared_ptr<trace::TracerProvider> api_provider = tracer_provider;
  trace::Provider::SetTracerProvider(api_provider);

  // Get Tracer From TracerProvider.
  tracer_ = trace::Provider::GetTracerProvider()->GetTracer("otel", "1.16.1");

Do you use cmake and how do you import otel-cpp.
Simular problems may happen when the macros are different between buiding otel-cpp and using it.

[yzhuang93]

CMake to build otel:

   -DCMAKE_CXX_FLAGS="-std=c++17" \
   -DBUILD_SHARED_LIBS=ON \
   -DBUILD_TESTING=OFF \
   -DWITH_EXAMPLES=OFF \
   -DCMAKE_POSITION_INDEPENDENT_CODE=ON \
   -DWITH_OTLP_HTTP=ON \
   -DWITH_STL=ON \
   -DCMAKE_CXX_STANDARD=17 \
   -DOPENTELEMETRY_ABI_VERSION_NO=1 \
   -DCMAKE_SKIP_RPATH=1

I just resolved this by turn both STL and Abseil OFF, I though I need to choose one from them, turns out that build without neither of them bypass this issue.
