David Spickett 831cf15ca6 [compiler-rt] Handle None value when polling addr2line pipe ... According to: https://docs.python.org/3/library/subprocess.html#subprocess.Popen.poll poll can return None if the process hasn't terminated. I'm not quite sure how addr2line could end up closing the pipe without terminating but we did see this happen on one of our bots: ``` <...>scripts/asan_symbolize.py", line 211, in symbolize logging.debug("addr2line exited early (broken pipe), returncode=%d" % self.pipe.poll()) TypeError: %d format: a number is required, not NoneType ``` Handle None by printing a message that we couldn't get the return code.
