    kidb_nug - 2009-01-31

    Hi,
    I compiled pixie under x86_64 linux. When I try to render the standard Blender scene from ribmosaic, pixie segfaults[1].

    Samplefile: http://video.blendertestbuilds.de/mosaic/Mosaic.tar.gz

    When I change the blender lamp to area,sun,hemi or else it works. Pixie, Blender, Mosaic work fine in 32bit environment.

    With kind regards
    KidB.

      I confirm this bug on my 64-bit FreeBSD, with a very similar backtrace (same calls on frames 0 to 8 inclusive). I haven't found anything more with a quick investigation. I won't time to explore this deeper in the next few days, but after that I check it more thoroughly, if a fix has not already been found by then.
