    Hi Sergey,<br>
    <br>
    I rebuilt with RelWithDebInfo target and ran a GDB backtrace after
    the crash. I'm including the corresponding generated crash log,
    which is still pretty similar to the old logs. Other than that
    backtrace, I'm not seeing any useful readout in console, either
    during GDB run or regular terminal run. <br>

        <div>The crash is happening somewhere in OIIO. Hard to tell from
          a backtrace created for a release build, but i _guess_ it's
          some locale crap which we were running into in the studio just
          another day. In order to confirm this idea, please check
          console output and tell us what kind of messages you've got in
          there.</div>

            fans. I recently did some tests for Thomas Dinges and the<br>
            experimental kernel and came across some long-standing
            render crash<br>
            issues. I've included some crash logs at the end of this
            mail. I build<br>
            from source and can run blender and work in it just fine,
            but when it<br>
            comes to rendering, all but one test scene crashes
            instantly, even with<br>
            CPU rendering. I'm about at my wit's end with this. This is
            a list of<br>
            things I've done trying to stabilize:<br>
            <br>
            Rebooting<br>
            Fresh builds from scratch<br>
            Building with CUDA TK 6.5, 7.0, 7.5<br>
            Build with "make full" to mirror official builds<br>
            Start blender with --factory-startup<br>
            Revert to earlier commits when it was previously rendering<br>
            Reinstall glibc (it shows up in crash logs)<br>
            Change make optimization levels from -O0 to -O3<br>
            Compiling with and without LLVM and OSL<br>
            Building single- and multi-threaded<br>
            Disable openMP<br>
            Build as minimally as possible<br>
            <br>
            I am able to run a buildbot build, so it has to do with my
            build setup<br>
            for sure. It seems to be part of the mesh export because I
            press render,<br>
            it opens the image editor and I watch it iterate through a
            list of geo<br>
            objects and crash. I've exhausted my knowledge of this build
            system,<br>
            since I'm not actually a programmer. If you have any hints,
            I'd be happy<br>
            to hear them.<br>
