Summary:
Duplicating object with particles system on it make Blender crashs
Detailed description
Ubuntu Lucid 64 - Blender 2.55.1 33528

Simple to reproduce :

Open Blender > select the default cube > add a particle system on it
and now let's do some instances of it with
> Alt+D > put it with LMB and duplicate gain until Blender crash...A little randomly thing but blender will crash for sure.

More: if you try to save your blend file between each duplicate particles operation (because you need to go forward:) you rapidly obtain a file that you can't open anymore. You can append some objects from this last file but not all
: some particle objects seems to become unloadable and make blender crash.

Bye

  • Sebastien: Hmm, I do get the crash, but it's at a random location every time, so I assume some pointer goes wrong somewhere in the duplication. What I can't replicate is creating a blend file that crashes on load. I such a file could help a lot in figuring out this bug, so could you please attach a file (as simple as possible scene) that has been saved in a corrupted state?

  • Note that may be useful to know: Even after the first duplication I get an error "Memoryblock free: pointer not in memlist" printed to the console.

  • Oh thank you Davis, don't know how that slipped past me! That led me straight to the cause. Fix committed! Closing the report.

    Note to Sebastien: The corrupted files probably can't be loaded even after this fix, but such corruption shouldn't happen with new files anymore.
