c++ firebase 段错误，linux，在 std::string::assign 无法访问地址 0xf 处的内存

Question

在 Linux 上使用 firebase C++ SDK 时出现问题，出于某种原因，它会从库内部抛出段错误。

我有下一个代码:

#include <iostream>
#include "firebase/app.h"
#include "firebase/analytics.h"
extern "C" int common_main(int argc, const char* argv[]);
int main(int argc, const char* argv[]) {
    return common_main(argc, argv);
}
    int common_main(int argc, const char* argv[]) {
    namespace analytics = ::firebase::analytics;
    ::firebase::App* app;
    ::firebase::AppOptions appOptions;
    appOptions.set_app_id("project-540NUMBERNUMBER67RR"); // changed
    appOptions.set_api_key("CoDeCoDeCoDeCoDeOcDeCoDeCoDeCoDeCoDeCod"); // changed
    app = ::firebase::App::Create(appOptions);
    analytics::Initialize(*app);
    return 0;
}

下一个堆栈跟踪:

在 x86_64 平台上。使用 Firebase C++ SDK 1.0 版。

所以问题可能在这段代码/否则 ABI/或 SDK 的某处。

有人遇到过类似的事情吗？

目前无法在 linux 平台上使用 C++ SDK。Google Firebase C++ SDK 在 Android 或 iOS 上使用 JNI/Java SDK 内部结构。它在 Linux 上不可用。
