Pants

looks like the problem of redirected output being null is back in #5247:

```[omerta pants (pr5247)]$ PANTS_ENABLE_PANTSD=True ./pants help | wc -l
       0
[omerta pants (pr5247)]$ PANTS_ENABLE_PANTSD=True ./pants help 
Pants 1.4.0.dev25 <https://pypi.python.org/pypi/pantsbuild.pants/1.4.0.dev25>

Usage:
  ./pants [option ...] [goal ...] [target...]  Attempt the specified goals.
  ./pants help                                 Get help.
...
```

failing in CI (test_pantsd_aligned_output) tho, so that’s good

and on the upside, it looks like #5174 is repaired by it

<https://travis-ci.org/pantsbuild/pants/jobs/322327152#L1150> &lt;- hung?

<@U054MQUPL>: i'm not seeing <https://github.com/pantsbuild/pants/issues/5174> fixed by <https://github.com/pantsbuild/pants/pull/5247> ... maybe i made more changes that broke things... whomp whomp.

confirmed on my side. I might have omitted the env var during testing :weary:

<@U054MQUPL>: <https://github.com/pantsbuild/pants/blob/6052b2aeef08303037058cf2d6aafe2299e2d273/src/python/pants/bin/goal_runner.py#L155> ... dead method maybe?

<https://github.com/pantsbuild/pants/pull/5263>

<@U06A03HV1> Do you happen to remember how you fixed `Exception message: /tmp/tmpW_aSo3/native_engine.so: undefined symbol: __gxx_personality_v0`? <https://travis-ci.org/pantsbuild/pants/jobs/325134541>

So this time it’s a runtime error not a compile time error

i... think it was a runtime error for me as well?

but: `Finished release [optimized + debuginfo] target(s) in 389.85 secs`

I thought that ended up being a linking issue vs the version of libstdc++ we were using in the docker image?
