On mac asan_symbolize script does not symbolicate frames coming from a dynamic library

By code inspection, asan does not attempt to symbolicate the frames coming from a dynamic
library:
    if filetype == "DYLIB":
      load_addr = "0x0"
    if DEBUG:
      print "atos -o %s -arch %s -l %s" % (binary, arch, load_addr)
    pipes[binary] = subprocess.Popen(["atos", "-o", binary, "-arch", arch, "-l", load_addr],
                         stdin=subprocess.PIPE, stdout=subprocess.PIPE,)


I also tested this out on a toy example; here the use-after-free happens in a dylib:

We mostly don't care about asan_symbolize
