Blend crashing, suspected Objects in -> Bounding Box

[enzyme69]

Problem statement

Blender crashes during reopening of blend. Suspected node: Objects in sourcing a mesh that supposed to output slicers ... but hard to explain.

1. This will crash: cross_section_like_a_boss_006.usdz.zip

2. Use Append to bring the node tree into empty Blend, and you can perhaps see the issue. I thought at first that I might have cyclic happening: Objects in -> make cutters from Bounding Box -> output cutters --> boolean into original object

But I think Objects In is causing crashing.

My first attempt to fix this crashing still failed: cross_section_like_a_boss_007_fixed.blend.zip

3. This I seems to fix it, I remove "Objects In" cross_section_like_a_boss_009_fixed.blend.zip

does the mac os version of blender have a debug executable, like windows has blender_debug_log.cmd... in the same folder and blender.exe , if you start Blender that way and load the .blend eventually it will dump an error log to a temporary file. You should start including that temporary log file in these bug reports.

007 loads fine here

[zeffii]

unfortunately it doesn't look like the debug log is revealing anything obvious..

[zeffii]

i'm going out on a limb here, but i think if there was a fundamental bug here it would be manifesting in other ways too. closing for now, but if you can reproduce with fewer nodes so as to narrow down a combo or single node.. then that will be much appreciated.

[zeffii]

also... not as usdz please.
