分配字符串时EXCEPTION_ACCESS_VIOLATION

我正在尝试将通过 jni 从 java 应用程序传递的字符串分配给 c++ 类实例的字段，但不断收到似乎不知从何而来的错误。我的应用程序在本机代码中崩溃，除了吸收之外什么都不做。

发生崩溃的 JNI 方法

[SCVXManager.java]
public static native void configure(String server, String realm, String username, String accountHandle);
[SCVXManager.cpp]
JNIEXPORT void JNICALL Java_mods_voicechat_SCVXManager_configure(JNIEnv * jenv, jclass jcl, jstring server,
jstring realm, jstring username, jstring accountHandle) {
auto app = SCVXApp::getApp();
auto serverStr = jenv->GetStringUTFChars(server, NULL);
auto realmStr = jenv->GetStringUTFChars(realm, NULL);
auto usernameStr = jenv->GetStringUTFChars(username, NULL);
auto accountHandleStr = jenv->GetStringUTFChars(accountHandle, NULL);
app->configure(serverStr, realmStr, usernameStr, accountHandleStr);
jenv->ReleaseStringUTFChars(server, serverStr);
jenv->ReleaseStringUTFChars(realm, realmStr);
jenv->ReleaseStringUTFChars(username, usernameStr);
jenv->ReleaseStringUTFChars(accountHandle, accountHandleStr);
}

发生崩溃的本机方法和相关变量的定义。

[SCVXApp.cpp]
void SCVXApp::configure(const string &server, const string &realm, const string &username, const string &accountHandle) {
m_server = server;
m_realm = realm;
m_username = username;
m_accountHandle = accountHandle;
}
[SCVXApp.h]
class SCVXApp {
private:
string m_realm;
string m_server;
string m_accountHandle;
string m_username;
<...>
}

需要注意的是，在此之前configure函数中分配的任何字段都不会在其他任何地方引用。

如果这很重要vivox_test.dll我的共享库是使用 CMake 使用 MSBuild 构建的

我不明白是什么导致了这个问题，我该如何解决这个问题。
