gdb backtrace from generated core file.
Hit this when trying to launch gnome-shell (-> mesa/llvmpipe) under a
vncsession on a ppc64 platform.
Using Head/Trunk LLVM, Head/Trunk Mesa/llvmpipe, fc17 based vncserver.
gnome-shell: /home/willschm/llvm/include/llvm/CodeGen/SelectionDAG.h:613:
llvm::SDValue llvm::SelectionDAG::getSetCC(llvm::DebugLoc, llvm::EVT,
llvm::SDValue, llvm::SDValue, llvm::ISD::CondCode): Assertion
`LHS.getValueType().isVector() == VT.isVector() && "Cannot compare scalars to
vectors"' failed.
This does look similar to existing bug 12716.
'bt' and 'bt full' from gdb core file attached.
