New Issue

System Information
OS: Ubuntu 13.10
Graphics card: AMD ATI Radeon mobility HD 5450, on opensource drivers.

Blender Version
IRIE Shinsuke's PPA, based on git master #dfa5ced

Exact steps for others to reproduce the error
Crashes occur whenever you click on the viewport with the left or right mouse-butoon. (Middle mouse-button however works fine)
Clicking on the UI doesn't give a crash.
Disabling or enabling VBOs does not make a difference.

Extra info
I have a hybrid graphics device, and recently figured out how to use the switching mechanic in Ubuntu.
The integrated card, an Intel device also on open source drivers, works perfectly fine with Blender.
I've attached three crash dumps. I hope these will be helpful.

I just experienced similar issue with bevel_object_problem.blend (ATI HD5730M, Debian64 testing, free drivers too).

Running a debug build with asan but out of gdb does crash too, but asan just reports a segfault, obviously outside of Blender scope. I could manage reproduce the crash with a gdb session (difficult!), but unfortunately, the backtrace is pure trash, which might indicate corrupted mem perhaps?

Probably this already has been fixed by updating the OSL library package in Mar 26. Now it uses the LLVM static library to avoid symbol conflicts with the graphics driver.

The problem shouldn't be in Blender because Blender actually doesn't use the LLVM shared library even if LLVM_STATIC=OFF.

@mont29 I guess your backtrace indicates the crash occurred in JIT-compiled code...

Well, we can't actually guarantee all builds made in all sorts of environment will 100% work, we can only ensure our own builds re fine.

@IRIEShinsuke, i'm not sure why it doesn't work for you (and how you check this even). It might also be up to how OSL is compiled or so.. If you'll find out culptrit in the blender configuration which causes troubles to you we're all up to fixing it in the upstream! :)
