newTransactionCoro() twice one one concurrent or too close making a memory stackoverflow

[drinkmilkcream]

problem: on windows or debian when running app().getFastRedisClient()->newTransactionCoro(); twice in one concurrent or too closing in time occur(Parallel) a memory overflow in line 84 ,position below:

    void resume() const {
        __builtin_coro_resume(_Ptr);
    }

i first found this problem i haved put two newTransactionCoro in one program block below,just single line,but when i using Apache for press testing it random broken in line 84，so i put this two line together below as a demotion below:

i am appreciated for anyone's help，thanks a lot!!! it is emergency!

a simple demo: broken in “ auto transaction = co_await app().getFastRedisClient()->newTransactionCoro();” call second time below all the time cpp

#include "testRedis.h"
#include <drogon/nosql/RedisClient.h>
Task<HttpResponsePtr> testRedis::test(HttpRequestPtr req)
{
    auto resp = HttpResponse::newHttpResponse();
            {
                auto transaction = co_await app().getFastRedisClient()->newTransactionCoro();
                co_await transaction->execCommandCoro("set key 1");
                co_await transaction->execCommandCoro("expire key 10");
                co_await transaction->executeCoro();
            }
            {
               //here is where collapsing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
                auto transaction = co_await app().getFastRedisClient()->newTransactionCoro();
                co_await transaction->execCommandCoro("set key 1");
                co_await transaction->execCommandCoro("expire key 10");
                co_await transaction->executeCoro();
            }
            resp->setBody("");

    co_return resp;
}
