Latest Slicer Preview Release crashes randomly on macOS Catalina

Support
1

Unfortunately, I can’t consistently reproduce this, but in the last couple of weeks Slicer has crashed many times. Today it’s happened when playing with the threshold in the Volumes module, but I’m not sure it’s related to that. I think the message in the shell is always the same, however, or very similar:

I hope others have faced the same issue, and that the developers can get an idea of where the issue might be coming from. Let me know if there’s anything else I can do to help.

I’m using today’s preview on macOS Catalina 10.15.5.

Thanks for letting us know. Have you built Slicer yourself or you use an official build? Which Slicer version is this? Has this version worked robustly before? Have you installed any extensions or added any modules? Do the two last lines (“Failed to lock QIOSurfaceGraphicsBuffer…” and “illegal hardware instruction”) appear right before the application crashes?

3

Official build.

Today’s preview, i.e. 4.11.0-2020-07-27 r29229 / 1217275. It has happened with other versions, I think all in this month.

I update Slicer often, so it’s hard to know.

I add a couple of modules and so some other stuff in my .slicerrc.py, but I haven’t touched it in months.

I don’t know, I see them in the console after Slicer crashes, so that seems to be the case.

@Sam_Horvath Have we ended up updating Qt version on Mac when we updated it on other platforms?

Looks like it is hitting the same assert that was crashing QtDesigner previously (See https://github.com/commontk/CTK/commit/0e1d94593d900fd144f50af38e3240063ab30484#diff-6f073d1f96143635788f382f18279749)

@lassoan Yes, the macOS nightly build is using Qt 5.15.0 which was done around the same time as the Windows upgrade.

6

First I thought so, too, but it is not a debug-mode build, so assert does not cause crash.

7

I got this message and crash today too with a local debug build of slicer on mac with Qt 5.15. Nothing about illegal hardware instruction though.

Is there a chance you can get a stack trace?

9

I did, but it wan’t informative. I’ll share it next time it happens.

Does this help?

That looks like what I’ve been seeing. Something between Qt and macOS.

12

Thank you @Fernando, this is very useful. In this stack trace the crash is triggered by ctkBasePopupWidget::setEffectGeometry(QRect) making a widget visible.

I did some web search for Qt crashes on MacOS Catalina and there were just a few that were vaguely similar, so most probably it is also something special about how Qt is used - most probably something in VTK but maybe in CTK.

@jcfr do you know if Paraview started to use Qt-5.15 yet?

Similar issue reported by another user:

I am experiencing a similar problem. My 3D Slicer didn’t crash until I returned to it after some time (I was working inside google docs for approx. 30minutes). I am not 100% certain, but I think it happened when clicking into the scene after returning.

Looks like an OpenGL/VTK issue to me. Here the Stack Trace:

Another occurrence reported by a user, just after starting Slicer, he started screen recording, then moved the Slicer application window a bit, then when the mouse was moved over the top-left corner of the 3D view, Slicer crashed. Probably it went over the push-pin icon.

I just got another crash with a stack trace like @Fernando’s. I believe the cursor just brushed over the pin icon.

It looks like it is the QAnimation used by ctkPopupWidget. Maybe the exit event happens and the widget is deleted before the animation gets started or something like that.

Perhaps the easiest would be to turn off that animation feature and just have popup appear and disappear instantly. I personally wouldn’t miss the animation and would prefer a more stable application.

Yes, that animation is not very useful and slownthings down, so I would not mind disabling it.

The popup window of slider widget in Volumes module caused crash, too.

We have fixed the issue (https://github.com/Slicer/Slicer/issues/5092), no crash should occur in Slicer Preview Releases downloaded 2020-08-11 or later. Let us know if you still experience similar problems.

I’ve also shortened the animation duration to 10% of the original, so popup windows appear immediately now.
