Created attachment 856774 [details] Test stl file that demonstrates issue PrusaSlicer crashes when attempting to slice an STL file into a gcode file. Steps to reproduce: - emerge prusaslicer (can be stable or ~amd64) - open a terminal and run the following two commands # Known to reproduce with a default config and my config, the next step may not be required mv ~/.config/PrusaSlicer ~/.config/orig-PrusaSlicer prusa-slicer - In Prusa Slicer that comes up: - Select Finish on the wizard that pops up - Press "Ctrl-I" to import an STL - Choose the STL that is attached (any STL may work - this is a small bracket I designed that I was trying to slice and print) - Click on "Slice now" button. Window should disappear. In the terminal window, you will see something like this: ------------------ (prusa-slicer:4431): Gtk-CRITICAL **: 13:33:10.000: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar 01:33:10 PM: Debug: window wxTreeCtrl(0x55c6948e4bb0, ) lost focus even though it didn't have it 01:33:10 PM: Debug: window wxTreeCtrl(0x55c6948e4bb0, ) lost focus even though it didn't have it /usr/lib/gcc/x86_64-pc-linux-gnu/12/include/g++-v12/bits/unique_ptr.h:445: typename std::add_lvalue_reference<_Tp>::type std::unique_ptr<_Tp, _Dp>::operator*() const [with _Tp = Slic3r::SpiralVase; _Dp = std::default_delete<Slic3r::SpiralVase>; typename std::add_lvalue_reference<_Tp>::type = Slic3r::SpiralVase&]: Assertion 'get() != pointer()' failed. Aborted ------------------ - I found that this issue is described on PrusaSlicer's github issue 9128 (I can't include links presently, as this is a new bugzilla account) - I applied the patch from PrusaSlicer's github with the commit has of 4b686af12db49500205ca15038fb7d651ccc4295 Added to ebuild, compiled, and now slicing works (and the resulting gcode prints on my Ender). (attaching additional files in updates)
