> You do realize that with this change, LLVM and Clang must now also be built with RTTI on, right? Otherwise, at least I get linker failures like these:

grumble, grumble, I was hoping that there were no dependencies that require clang to be built with RTTI. I'll undo this change. std::tr1::shared_ptr requiring RTTI looks like a bug in libstdc++. Maybe we can get the owner of the lldb-linux buildbot to update g++ on that machine.
