Crash after rotating sliced part in layer view

[Hugoz12]

Version

1.35.5-prusa3d-linux64

Operating system type + version

Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2 (2017-04-30) x86_64 GNU/Linux

Behavior

• Add a part
• view it in "Layers" tab
• slice it
• rotate it by clicking the 45degree buttons
  --> Slic3r crashes
  (When the GUI is started via terminal it becomes unresponsive without an error message in the terminal. Ctrl+C is needed to close it.)

• Expected Results

• layers disappear until you slice again
  This actually happens when you first slice the part then change to "Layers" tab and rotate. Reappears after slicing. But crashes if you rotate after that.

Auto-processing deactivated. Tested with 2 models.
If you can't reproduce I'll provide the parts and config.

- Add a part - view it in "Layers" tab - slice it - Did you switch to the layer view here? Or the 3D preview? The "Layers" tab has the buttons disabled on Windows. Maybe they shall be disabled on Linux as well? - rotate it by clicking the 45degree buttons --> Slic3r crashes Still in the layer view? Or the 3D preview? (When the GUI is started via terminal it becomes unresponsive without an error message in the terminal. Ctrl+C is needed to close it.) - *Expected Results* - layers disappear until you slice again This actually happens when you first slice the part then change to "Layers" tab and rotate. Reappears after slicing. But crashes if you rotate after that. If you slice, then go to layer view, then back to 3D view, delete an object, load another one and then repeat the "crashing" scenario once again, will it crash again?

No I switched to the layers tab before slicing.

The "Layers" tab has the buttons disabled on Windows. Maybe they shall be disabled on Linux as well?

Good idea. Maybe it's just an oversight on Linux because it doesn't show anything anyway.

• rotate it by clicking the 45degree buttons --> Slic3r crashes

Still in the layer view? Or the 3D preview?

Yes all done in Layers tab.

If you slice, then go to layer view, then back to 3D view, delete an object, load another one and then repeat the "crashing" scenario once again, will it crash again?

Yes it still crashes.

@FidelCapo was not able to reproduce this issue. He tested on 1.35.5 and on our latest integration build 1.40.0-alpha.249.

There is an issue with the cancellation of the slicing core, which is still partially written in Perl. I suppose this issue will go away in 1.41, when the complete slicing backend will be rewritten into C++.

We hope we fixed your issue by refactoring the background processing code.
Please retest with 1.42 alpha once it is released this or the next week. Closing.
