[BUG] - *** stack smashing detected ***: terminated Aborted (core dumped)

[SimonBirrell]

I appreciate that this may be a problem unique to my machine:
Ubuntu 24.04 AMD Ryzen™ 5 7640U w/ Radeon™ 760M Graphics × 12

Easy3D is working fine via the Python bindings for pointcloud manipulation. Any sort of visualization though, be it through the renderer or viewer, gives a core dump. For example:

renderer = easy3d.OffScreen()
model_pathname =  easy3d.resource_directory() + "/data/bunny.ply"
model = easy3d.PointCloudIO.load(model_pathname)
renderer.add_model(model)
renderer.render(image_pathname) 

This produces the output:

*** stack smashing detected ***: terminated
Aborted (core dumped)

I suspect it's something to do with OpenGLm as lline 678 of framebuffer_object.cpp looks like this:

    case GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT:
        LOG(ERROR) << "Framebuffer incomplete, missing attachment.";
        break;

I'm running the open-source AMD drivers. I tried installing the proprietary AMD drivers, messed up, and spent hours painfully recovering my operating system. I'm really just checking in to see if it's anything anyone else has already seen, before I return to doing difficult and possibly pointless upgrades!

This is the latest release Easy3D-v2.6.1, installed as a wheel.

Thanks!

Here's a quick variation:

renderer = easy3d.OffScreen()
model_pathname =  easy3d.resource_directory() + "/data/bunny.ply"
model = easy3d.PointCloudIO.load(model_pathname)
renderer.add_model(model)
print(f"Rendering to {image_pathname}")
# renderer.render(image_pathname)

viewer = easy3d.Viewer("Easy3D Viewer")
viewer.add_model(model_pathname)
viewer.run()

Here the result looks like this:

Aborted (core dumped)

In this case, the little viewer window pops up with a black background, no other image and disappears after about a second when the core dump happens.

And yet, when I load in pointclouds, transform them, output meshes and so on, it works perfectly. It appears to be just the visualization tha fails.

[LiangliangNan]

You mixed off screen rendering with the normal viewer, but I don't know if this is the root cause of the issue. Can you comment out the following lines of code and see if the problem still exists? renderer = easy3d.OffScreen() model_pathname = easy3d.resource_directory() + "/data/bunny.ply" model = easy3d.PointCloudIO.load(model_pathname) renderer.add_model(model) print(f"Rendering to {image_pathname}") Best, -- Liangliang

Yes, if I just run

model_pathname =  easy3d.resource_directory() + "/data/bunny.ply"
viewer = easy3d.Viewer("Easy3D Viewer")
viewer.add_model(model_pathname)
viewer.run()

I still get a core dump.

I'm not sure if this is relevant, but I tried running glmark2 to check if OpenGL is running. All the tests seem to display fine. There is one persistent warning (?) in the logs though:

I'm wondering if the OpenGL implementation of AMDGPU is missing something that Easy3D needs. On the other hand, other 3D programs like CloudCompare seem to work ok.
