Qt 只是一个小于'；世界你好'；QML的错误导致cygwin出现分段错误

我正在尝试将QML与cygwin一起使用

我准备了这个非常简单的代码，

simple.qml

import QtQuick 2.0
Rectangle { }

然后，

qmlscene-qt5 simple.qml

导致分段错误。我怎样才能避免塞法卢茨

软件版本如下所示：

• Windows：8.1 64位和10 64位都会导致segfault
• cygwin:2.5.0-1 x86
• xorg服务器：1.18.2-1
• LibQt5Core5、qt5声明性工具等：5.5.1-1

顺便说一句，此代码不会导致segfault

import QtQuick 2.0
import QtQuick.Window 2.0
import QtQuick.Controls 1.0

Window{
    title: 'window'
    Label{
        // text: 'hello, world!'
        // If I uncomment the above line, a segfault emerges.
    }
}

谢谢你阅读这个问题

仅供参考，

gdb

日志如下所示。我执行

gdb/usr/bin/qmlscene-qt5

，并在segfaulted之后检查
