provide a little more information before calling std::terminate

[willie]

I've incorporated OpenTelemetry into my program and on certain execution paths, especially on Linux, I get terminate called without an active exception or similar kinds of messages.

If I take out my OpenTelemetry initialization/cleanup functions and leave the null Otel spans and logs in there, nothing crashes. I have exception handlers defined, but there are a few cases where a raw std::terminate is called from the library.

For example:

opentelemetry-cpp/api/include/opentelemetry/nostd/span.h

Line 103 in 848db57

std::terminate();

I have no idea if this is the bug or not, but it makes it harder. I would expect a library to log something if it's going to call terminate.

I commented out my logging initialization today and logging calls on Linux now:

1. do nothing (expected)
2. no longer crash with terminate

Logging calls on Mac work just fine before/after.

This is the init call I commented out:

void InitLogger() {
	// Create ostream log exporter instance
	auto exporter = std::unique_ptr<logs_sdk::LogRecordExporter>(new otlp_exporter::OtlpHttpLogRecordExporter);

        auto processor = logs_sdk::SimpleLogRecordProcessorFactory::Create(std::move(exporter));
	std::shared_ptr<logs_api::LoggerProvider> provider =
			logs_sdk::LoggerProviderFactory::Create(std::move(processor), GetResource());

	// Set the global logger provider
	logs_api::Provider::SetLoggerProvider(provider);
}

I have a stacktrace now for the termination call:
