Help with failed build tests

• Module (and version) (if relevant):

Hi, I have some failed build tests on RHEL 7 that I would like to consult.

These two have been failing for v4 and v6 too:

=== release test-net-better-error-messages-port-hostname ===

assert.js:60
  throw new errors.AssertionError({

These fail only with v8:

=== release test-util-inspect ===

/builddir/build/BUILD/node-v8.1.2/test/parallel/test-util-inspect.js:85
assert.strictEqual(util.inspect(process.stdin._handle._externalStream),
                                                     ^

I use shared zlib-1.2.7, compared to zlib-1.2.11, so maybe that fails this test:

Path: parallel/test-zlib-failed-init
assert.js:60
  throw new errors.AssertionError({
  ^

@kasicka Did you get them to pass yet? Let me know if you still need help.

[kasicka]

Nope, they still fail, plus I have test-regress-GH-746 failing randomly on various archs. I can't find a log, but the test times out.

I believe the issue that made parallel/test-util-inspect flaky was fixed recently, although that may not have made it into a release yet.

parallel/test-net-better-error-messages-port-hostname and parallel/test-net-connect-immediate-finish failing means your DNS resolver returns something unexpected for invalid hostnames. Might be a bug in the test, might be a bug in your network.
