"pure virtual method called" in Linux (no problem on Windows) #942

Hi

I am using cpprest 2.10.1 with boost 1.60 and I get an error: "pure virtual method called" (I also tried with cpprest 2.10.6 and boost 1.68 and I had the same issue).

With gdb I have the following stack trace:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

The code I used:
` void MCLSRestClient::AffectDevice(const std::string & sDeviceId) {
std::cout << MCLSRestClient::AffectDevice BEGIN << sDeviceId << std::endl;

	static web::http::http_request oRequest;
	BuildAffectDeviceRequest(oRequest, sDeviceId); // Info is added to oRequest

	std::cout << "MCLSRestClient::AffectDevice Request Built" << std::endl;
	// m_oClient is web::http::client::http_client
	pplx::task<void> m_oCurrentTask = m_oClient.request(oRequest).then([this](http_response oResponse) -> bool {
		std::cout << "MCLSRestClient::AffectDevice First attempt" << std::endl;
		return OnAffectDeviceResponse(oResponse);
	}).then([&, this](bool bRetry) {
		std::cout << "MCLSRestClient::AffectDevice Might retry" << std::endl;

		if (bRetry) {
			std::cout << "MCLSRestClient::AffectDevice Retry" << std::endl;

			// Retry the request with the new AccessToken
			web::http::http_request oRetryRequest;
			BuildAffectDeviceRequest(oRetryRequest, sDeviceId);

			m_oClient.request(oRetryRequest).then([this](http_response oResponse) {
				OnAffectDeviceResponse(oResponse);
			}).wait();
		}
	});

	std::cout << "MCLSRestClient::AffectDevice END" << sDeviceId << std::endl;
}`

The output I get is
MCLSRestClient::AffectDevice BEGINA61FABC67F2F1AE535060A7558DCFECB51B9D539
MCLSRestClient::AffectDevice Request Built
MCLSRestClient::AffectDevice ENDA61FABC67F2F1AE535060A7558DCFECB51B9D539
pure virtual method called
terminate called without an active exception
Aborted

I also tried with empty lambda expressions and I still have the same pure virtual method called error. The same code works fine on Windows.
