Crash with "Complete individual objects"

[friedelwolff]

I realise this might be an upstream bug, but I thought I'll start here, since I'm using version 2.5.0 from flathub.

When slicing with the option Print Settings -> Output options -> Complete individual objects enabled, I get a crash with this error:

/usr/include/c++/11.3.0/bits/stl_vector.h:1045: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, _Alloc>::size_type) [with _Tp = double; _Alloc = std::allocator; std::vector<_Tp, _Alloc>::reference = double&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__n < this->size()' failed.

It is reproducible on the project where I wanted to use that setting, but on another, no crash occurs. I assume you'll need more information, but I'm not sure what is best. I attach the .3mf file (zipped) as first guess to what you'll need to reproduce.

Hi @friedelwolff ..

thanks for your report. Can you please do us a favor, can you download the official AppImage with Gtk3 from Prusa3D and do the same test?

Download: https://github.com/prusa3d/PrusaSlicer/releases/tag/version_2.5.0

That would be a big help to decide where this issue belongs, if the AppImage has the same issue then it might be an upstream bug.

Let us know.

Thanks a lot!

Hi to all, I can reproduce this only with flatpak version, the appimages version seems to work fine.

From backtrace seems to crash during the rendering of the layers slider (maybe there is a problem with wxwidget), I will investigate on this during the weekend.

awesome 👏

Hi @friedelwolff, sorry for the long delay in replying, can you test the build in this pull request and tell me if it solves the problem for you?

[friedelwolff]

Thank you for the work on this! I won't be able to confirm any time soon, unfortunately. I might only get back to these things in the new year.
