Also I have noticed my stack trace does not show Golang symbol names like some example stacktraces in #850 do have. What am I missing to make the stack traces to show Golang symbols? I dit verify with readelf that the hello shared library has debugging info in it. Is it because upload_manifest.py strips all *.so files?
