QtCreator random hangs on Windows 10



  • Hello,
    My QtCreator "Qt Creator 4.8.0-rc1 (4.7.84) Based on Qt 5.12.0 (MSVC 2015, 32 bit)" on Windows 10 (up to date on patches) hangs randomly. Today, it repeatedly hangs when I am trying to paste code into a newly created class. In the past it has shown tendencies to hang on random operations.

    Is it normal for QtCreator to hang? How do I diagnose these hangs?

    Thanks.

    No. Normally it is rock-stable. I used the 4.8-beta at work and didn't have problems. Unfortunately with 4.8 on Windows 7 I have the same problems as you and have not been able to isolate the problem. It even happens with Clang Code Model disabled. On Linux all is fine.

    I installed a 4.8.1 snapshot on Friday and will see how that behaves the next days. In case you want try too: http://download.qt.io/snapshots/qtcreator/4.8/4.8.1

    Otherwise downgrade to 4.7.2. It works like a charm.



  • Also, why does the Qt installer install 4.8 RC1 32 bit, instead of 64 bit? I am wondering is the cause of the frequent hangs? My 4.8 RC1 installation is annoying unusable....grrrrr. I just don't know how to resolve this issue.

    If I downgrade to 4.7.2, will it be able open/build the projects defined using 4.8 RC1?

    Where are the logs written during crashes? What makes these crashes worse, is not being to figure out the crashes. They happen during different actions: saving forms, creating slots, copy/pasting...

    @JohnGa 4.8RC1 is a release candidate, it can still have issues. I'm not sure why you install a release candidate.
    32bit build should be just fine as Windows 64bit executes 32bit software.
    It should be possible to open projects created with 4.8RC1 in 4.7.2
    "Where are the logs written during crashes?" - on Windows I guess in the Event Log in MMC.
