Thanks for the report! asan support requires the compiler-rt subproject (found in upstream build instructions for clang SVN), I will update clang-9999 to also check out this module
clang-9999 now also fetches compiler-rt trunk (we will see when 3.1 release gets ready if compiler-rt can be split in a separate package) It also installs asan_symbolize.py, until this is added directly in compiler_rt
Fix confirmed. Thanks for the speedy fix!
