Hi, What is the best way to debug an llc crash using bugpoint? I am getting the following crash that I would like to reduce llc: /home/vadve/aggarwa4/llvm29/llvm-2.9/lib/MC/MCAsmStreamer.cpp:273: virtual void<unnamed>::MCAsmStreamer::EmitLabel(llvm::MCSymbol*): Assertion `Symbol->isUndefined() && "Cannot define a symbol twice!"' failed. 0 llc 0x00000000013ae046 1 llc 0x00000000013ae5d4 2 libpthr...

David, Another alternative for darwin8 would be to bootstrap llvm/clang 3.0 using the clang from the fink llvm29 package (since clang 2.9 should build fine against gcc-4.0.1).

Are there any plans to add CMake support to the build of SAFECode? Also are there any current instructions for building llvm/clang with SAFECode support from current svn? Jack
