Strawberry crashes seemingly randomly while playing music. Qt 6 bug: QTBUG-92188 #670

Closed RillingDev closed 3 years ago

Check the Changelog to see if the issue is already fixed: https://github.com/strawberrymusicplayer/strawberry/blob/master/Changelog

-> did not see issue description matching this one. Tested with Strawberry-0.9.1-26-gb224aeb0-Qt6-x86_64.AppImage and had another crash.

Describe the bug Strawberry crashes seemingly randomly playing music. I know that is very general but I thought i create an issue to track this in case others have the same issue and have noticed a pattern. The following core dump backtrace data is available:

To Reproduce Keep strawberry running playing music? see above, I have not found a consistent way to reproduce this yet.

Expected behavior Strawberry does not crash,

Screenshots: n/a

System Information:

Additional context If the full 1GB core dump is useful, please tell me so I can send it to whoever investigates

jonaski commented 3 years ago

I'm pretty sure I saw the exact same assertion while I was working on the cover manager and tag editor. However I could only reproduce it with Qt 6. But it disappeared so I thought it was a Qt bug that had been fixed in Qt 6.0.2. I can no longer reproduce it, and it has not crashed for me for weeks, but I run the Qt dev branch on my main music PC, which is Qt 6.2, on the development machine I currently have 6.0.2, but no problems there either.

RillingDev commented 3 years ago

Hmm, interesting. As I could not find an easy way to use a newer version of Qt on my system without some work, I will try to update this issue once a newer Qt version becomes available for my system.

jonaski commented 3 years ago

I downgraded Qt on my music box to 6.0.2 but still can't reproduce a crash, can you tell if it's crashing on a specific album cover or not? The backtrace is showing ImageUtils::ScaleAndPad, which is used all over the place in strawberry to scale and pad covers. But I can't see anything wrong with the code there. You can probably reproduce it more easily if you try open the cover manager so that all the covers are loaded.

RillingDev commented 3 years ago

Opening the cover manager does not cause any crashes, Interestingly the same track+cover that works fine one time crashes randomly another time, so I doubt its related to a specific cover.

However, I ran tests with verbose logging and the one time i got the crash the following was logged before the core was dumped: "**** stack smashing detected ***". Maybe that helps trace down the issue.

jonaski commented 3 years ago

Ah! It's because they compile with stack protection.

jonaski commented 3 years ago

I can't reproduce this, even when compiling with -fstack-protector-all and -fstack-protector-strong.

RillingDev commented 3 years ago

What a weird and specific issue this is then 😅. Here is more of the verbose log when a crash happens:

(As noted before, this specific track for example works without issues if i play it after the crash)

I will also upload the full core dump and DM you a link, maybe that helps.

Thanks for investing time in this issue by the way, even if it seems very hard to analyse!

jonaski commented 3 years ago

I suspect the bug is in Qt 6. I opened a bug report here: https://bugreports.qt.io/browse/QTBUG-92188

jonaski commented 3 years ago

I was working on a different program over the weekend, and I can reproduce the same crash with Qt 6.0.2 pretty consistently when I run the program in Qt Creator debug. But if I try to run some QImage::scale code in a loop on it's own I can't reproduce it, so it looks to be in combination with something else. The program is here: https://github.com/jonaski/qtgiphy It's a program that displays GIF's from giphy.com

aminvakil commented 3 years ago

Same issue I guess, running strawberry 0.9.2, qt6-base 6.0.3.

I can still reproduce the crash with Qt 6.0.3 and the latest Qt dev branch with my qtgiphy program. Not a single crash with Qt 5.15.2

jonaski commented 3 years ago

The following code can reproduce the bug when running in Qt Creator debug (qt 6):

  for (int i = 0 ; i <= 1000 ; ++i) {
    QFile file(":/something-on-me.jpg");
    if (file.open(QIODevice::ReadOnly)) {
      QByteArray data = file.readAll();
      file.close();
      QImage image;
      if (image.loadFromData(data)) {
        for (int x = 0 ; x <= 2000 ; ++x) {
          QImage image_scaled = image.scaled(QSize(x, x), Qt::KeepAspectRatio, Qt::SmoothTransformation);
          qDebug() << x << image_scaled.size();
        }
      }
    }
  }

It runs fine with Qt 5.15.2

initramfs commented 3 years ago

Bug is reproducible on my system as well (Arch Linux) with Qt 6.0.3. I've submitted additional debugging information to the linked Qt bug here.

jonaski commented 3 years ago

Patch for qtbase available for testing: https://codereview.qt-project.org/gitweb?p=qt/qtbase.git;a=patch;h=b00408657e666cb5906c8da7dc10c33f8ebf258d

Let's leave this open until the next Qt 6 version with a fix.

jonaski commented 3 years ago

Unfortunately I can no longer reproduce the crash testing with 6.1, so I can't say if the patch fixes it or not. @initramfs Can you test with the patch?

jonaski commented 3 years ago

Qt 6.1.1 is available now, should have the fixes for this bug.

jonaski commented 3 years ago

I tested strawberry on a newer laptop over night where I could reproduce the crash with 6.1.0, and it seem to be fixed with Qt 6.1.1.

RillingDev commented 3 years ago

Have been running strawberry with Qt 6.1.1 for ~5 hours now, no crashes. Looks good! Thanks again for investigating (and fixing) this issue, even though it was not even in strawberry itself!
