Don,
     My mistake. The llvm fink packaging files we are using had a build
script with...

         # Do not want -DNDEBUG, cause linker errors (undef symbols)
        # LLVM_ENABLE_ASSERTIONS:ON should have removed -DNDEBUG
        # but it doesn't, so hack it out of cmake file
        test "$enable_assertions" = OFF ||
                sed -i.orig -e '/-DNDEBUG/s|.*|#&|'
cmake/modules/HandleLLVMOptions.cmake

 which isn't problematic but later in stage1 the script used...

        # kill -DNDEBUG with fire
        sed -i.orig -e 's| -DNDEBUG||g' CMakeCache.txt

Changing that to...

        # kill -DNDEBUG with fire
        test "$enable_assertions" = OFF || sed -i.orig -e 's| -DNDEBUG||g'
CMakeCache.txt

eliminated that particular build failure in llvm trunk.
