Erase tool segfault

[propugnator101]

erase tool makes the app close itself on windows 11

[BigBoyBarney]

The app crashes on Windows 10 as well using OpenTabletDriver. I built the current main branch
https://github.com/mbrlabs/Lorien/commit/d1aba0753aa4354ec41b93a52510f76540d2a3d9
and it crashes there too.

I believe I have the same bug. I'm on Fedora Linux and the program closes with "Segmentation fault".
On my machine, the error can be instantly produced by spamming penstrokes and the "b" and "e" key.

Duplicate of #153 which has been resolved in v0.6.0 dev.

[BigBoyBarney]

It has not, I built the main branch and it still crashes

[hansemro]

Can you share Godot's debugger output as it crashes?

[BigBoyBarney]

Do you mean the godot log files in %appdata%?

Thanks!

@mbrlabs I think we should also release debug binaries since these will dump a backtrace in the log file. This could also be useful for distinguishing engine crashes.

[hansemro]

@BigBoyBarney Can you try this debug-enabled build and share log? https://github.com/hansemro/Lorien/releases/tag/v0.6.0-debug-test

[BigBoyBarney]

Now that's interesting. This version doesn't crash.

https://github.com/BigBoyBarney/Lorien/actions/runs/4096398750#artifacts
https://github.com/BigBoyBarney/Lorien/suites/10787140016/artifacts/542252558

The one I built from this 2 weeks ago (which should still be identical to the main branch) did. The artifact was Lorien_v0.6.0-dev.exe, so it is the right branch right? Or is main not the latest one?

Thanks for your help!

[mbrlabs]

Is this still crashing for you guys? Here are some fresh (release) build artifacts using Godot 3.5.2: https://github.com/mbrlabs/Lorien/actions/runs/5770814754

I can confirm that as of 02/22/24, I am experiencing this crash. The eraser only seems to crash the program after lines have been drawn with a tablet pen. Using purely a mouse does not cause the crash, although trying to erase with the mouse after drawing a line with the tablet pen will still crash the program.

I am hoping this additional information is relevant:

• OS: Windows 10
• Tablet: XP-PEN Artist15.6 Pro Tablet
• Graphics Card: NVIDIA GeForce RTX 2060 SUPER

I confirm that this is still an issue when drawing with a pen. However, in my case, it's the pen's eraser that causes the segfault. The application's eraser behaves as expected.

This is on Linux, Ubuntu 22.04, x86_64, Wacom Bamboo Create

I recently ported the project to Godot 4.3, so a lot has changed. Could any of you test this again? Unfortunately i could never reproduce this.

Here are the latest CI builds: https://github.com/mbrlabs/Lorien/actions/runs/10579945908
