libcpprest.so.2.10 crashed with a nonexistent URL instead of throwing exception

[everdancer]

I intentionally used an invalid URL to create http_client, e.g. mp_client = new http_client(U("http://not.present.site.com"));, then I started a GET request. I expected an exception, but the process crashed directly.

Program terminated with signal 11, Segmentation fault.

I'm using the latest release of sdk, OS is CentOS7, and boost version is 1.69.0.
Is this a case where exception is not supported yet?

[barcharcraz]

can you post some source code that reproduces this?

[everdancer]

@barcharcraz

m_callback = a_callback;

//a_uri can be any nonexistent URL.
mp_client = new http_client(a_uri);

auto query = uri_builder().append_path(U("storelist")).to_string();

// Get the response.
mp_client->request(methods::GET, query)
.then([&](http_response response) -> pplx::task<json::value>
{
    // Check the status code.
    if (response.status_code() == status_codes::OK)
    {
        // Convert the response body to JSON object.
        return response.extract_json();
    }
    // return an empty JSON value
    return pplx::task_from_result(json::value());
})
// Parse the user details.
.then([&](pplx::task<json::value> previousTask)
{
    try
    {
        m_callback(previousTask.get());
    }
    catch (const exception& e)
    {
        A7C_LOG_ERROR(A7C_TDRSOURCE, "ProteanTask::getStoreList - " << e.what());
        m_callback(json::value());
    }
}).wait();

I figured out that the issue is caused by boost version (my env has both 1.53 and 1.69). Once removing 1.53 and rebuiding, it works fine.
