Question

我在此行上有应用程序崩溃，然后在Android 4.4.2 x86模拟器上运行应用程序：

QQmlApplicationEngine engine;

例外是：SIGFPE Arithmetic exception

emptyQml.pro

QT += qml quick
CONFIG += c++11
SOURCES += main.cpp
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

的main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>
int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    QGuiApplication app(argc, argv);
    QQmlApplicationEngine engine; // <============================== exception is here
    //engine.load(QUrl(QLatin1String("qrc:/main.qml")));
    return app.exec();
}

这是一个最小的例子。真正的应用程序在Android 4.4.2的客户端设备上崩溃。

在GoolePlay控制台中，有针对Android 4.4的崩溃报告：

qt：5.8 ndk：android-ndk-r10e jdk：jdk1.8.0_101 蚂蚁：apache-ant-1.9.7

有什么想法吗？
