Summary:
SubSurf IcoSphere as Boolean Modifier on Cube Causes Render Crash
Detailed description
i) what causes crash
subsurf ico sphere is used as a boolean (in difference) mode on a subdivided cube, causes crash on render.

*note not subsurf ico sphere doesn't cause render crash. subsurf on a ico sphere causes alots of poles and not a good mesh overall due to subdivision of triangles nevertheless.

error msg:

11/17/10 9:00:00 PM [0x0-0x2a62a6].org.blenderfoundation.blender[11602] Boolean code using new merge technique.
11/17/10 9:00:26 PM com.apple.launchd.peruser.501[92] ([0x0-0x2a62a6].org.blenderfoundation.blender[11602]) Job appears to have crashed: Bus error


ii) how to reproduce

try render the attached scene, or do these steps

a) subdivide the default cube some times in edit mode
b) add a new object, a ico sphere.
c) hit ctrl+2 to give it a subsurf modifier of level:2
d) add modifier boolean on cube
e) change it to difference, and to use the icosphere
f) hit render


iii) system info
version 2.55 (sub 0), revision 33141. Release
build date: 2010-11-17, 19:46:35
platform: Darwin:64bit

  • I guess someone just quickly fixed this one directly or indirectly? :S I tried an older build and reproduced the crash every time I repeated the procedure. Just built right now and it works. Can you test again with a newer build?

  • Sender: sneg negr
  • Yeah. I seems something has just been changed in the mesh/boolean code. I can open your file with fresh the build, but it draws incorrectly in viewport and render.

  • err. Sorry. I had tested the .blend of another report. Yours doesn't have any problem.

  • I'm unable to reproduce that bug.

    SVN r33141 / Ubuntu 10.10 64 / GTX 275

  • nope just svn update, and rebuild.

    At revision 33143.

    and it still crashes upon rendering. same error msg. in log.

  • works for me, 64bit linux, debug build. r33150.

  • I've got no crash when rendering, but when i'm enabling VBO at my notebook and they trying to select icosphere it crashes.
    Happens at my laptop: linux 64bit, imtel gme965. Can't check at "normal" video card atm. Maybe it's videodriver issue.

  • removed all my install files, svn up, and rebuild. but still same issue crashes on rendering.

    I have by def. VBO's turned off. It could cause some very hard crashes with VBOs. I tried with VBO's on but no difference crashing when hitting rendering.

    I'm attaching my whole sysinfo.txt , i have a nvidia gt8800 gfx card and no other issues related to graphic drivers. and the latest update of 10.6.5 OSX.

    Maybe this is a OSX related thing and thus connected to GHOST: anyone on mac that could try this?

  • renders fine in OSX 10.5 ppc.
    However, your crash report shows an issue in selecting objects. I know there are issues using the UI while rendering...

    Also verify our official 2.55 release from blender.org!
    And, if you compile yourself, ensure you don't change compile flags for extra optimization, can also cause errors.

  • I'm building w/o flags. still crashes in 2.55.0 r33251.
    downloaded 2.55.0 beta from blender.org, also crashing.

    I'm not doing anything in the UI while rendering, as soon it goes into render view it's black and it crashes.

    i tried to test with luxrender as engine, it also crashes before luxrender is initiated. dunno if that is any help.

  • can you run in gdb, and provide a stack trace? (type "where" in gdb)
  • Date: 2010-11-26 04:20
  • Sender: Brecht Van Lommel
  • I can redo the crash on Mac OS X with a debug build. The backtrace is more than a 1000 levels deep, it seems to be running out of stack space. Doing the exact same boolean operation in the viewport works, maybe it's because the stack is slightly shorter to begin with, or threads have a smaller stack

  • Fix in svn. Pass the stl vector by reference instead of by value, saves stack space.
