QMLの 'Hello world'よりも小さいコードだけがcygwinでセグメンテーション違反を引き起こします

CygwinでQMLを使用しようとしています。QMLの 'Hello world'よりも小さいコードだけがcygwinでセグメンテーション違反を引き起こします

この非常に単純なコードsimple.qmlを用意しました。

import QtQuick 2.0 
Rectangle { }

次に、qmlscene-qt5 simple.qmlは、セグメント化エラーを引き起こします。どのようにsegfalutsを避けることができますか？

ソフトウェアのバージョンは以下の通りです：

  • Windowsの場合：2.5.0-1のx86
  • のxorg-サーバー：1.18.2-1
    • 両方8.1 64および10 64原因が
  • Cygwinをセグメンテーションフォールト
  • LibQt5Core5、qt5-宣言型・ツールおよび等：5.5.1-1
    • ちなみに

、このコードは、セグメンテーションフォルトが発生することはありません。

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. 
    } 
}

この質問をお読みいただきありがとうございます。

FYI、gdbログを以下に示す。私はgdb /usr/bin/qmlscene-qt5を実行し、segfaultedの後にwhereを調べます。

32bit版にも同様の問題があり、バージョン11.0.9-1

にDRI-ドライバを元に戻す試してみてください。 https://cygwin.com/ml/cygwin/2016-04/msg00254.html

ありがとうございました。あなたが言ったように、 'ドライドライバー' 11.0.9-1ではコードがうまく機能します。 （11.0.9-2では 'glxgears'でもセグメンテーションが起こります） –
