Awesome if you want to give it a try :) Note that support for in-process symbolization is already there. You may simply link in the library with functions __sanitizer_symbolize_code and __sanitizer_symbolize_data, and these functions will be picked up by ASan runtime and used instead of forking llvm-symbolizer. See InternalSymbolizer class in sanitizer_symbolizer_posix_libcdep.cc. We use this behavior in our private setup (i.e. we link with hermetic library version of llvm-symbolizer tool, built by a huge and ugly script).
