Runtime error when executing a simple example (gcc 8.3)
I built a simple example with sanitizer (added the parameter -fsanitizer = address, undefined in CXX_FLAGS). OS Debian 10.2 (gcc 8.3).
#include
#include <cpprest/http_client.h> #include <cpprest/filestream.h> #include <cpprest/uri.h> #include <cpprest/json.h> using namespace utility; using namespace web; using namespace web::http; using namespace web::http::client; using namespace concurrency::streams; int main() { // Create user data as JSON object and make POST request. auto postJson = pplx::create_task( { json::value jsonObject; jsonObject[U("first_name")] = json::value::string(U("atakan")); jsonObject[U("last_name")] = json::value::string(U("sarioglu")); return http_client(U("https://reqres.in")) .request(methods::POST, uri_builder(U("api")).append_path(U("users")).to_string(), jsonObject.serialize(), U("application/json")); }) // Get the response. .then([](http_response response) { // Check the status code. if (response.status_code() != 201) { throw std::runtime_error("Returned " + std::to_string(response.status_code())); } // Convert the response body to JSON object. return response.extract_json(); }) // Parse the user details. .then([](json::value jsonObject) { std::wcout << jsonObject[U("first_name")].as_string() << " " << jsonObject[U("last_name")].as_string() << " (" << jsonObject[U("id")].as_string() << ")" << std::endl; }); try { postJson.wait(); } catch (const std::exception &e) { printf("Error exception:%s\n", e.what()); } return 0; }

If without a sanitizer it is naturally not there. More precisely, it is, just no one tells you about it (such as sanitizer). Any thoughts on how to fix this?
Has that issue been addressed? Is there any solution to this? I am running to the same problem on RHEL8 with ASAN build.
