snapshot generation fails on armv8: https://ci.nodejs.org/job/node-test-commit-arm/2474/nodes=armv8-ubuntu1404/console

Updated to 5.0.71.19.
CI: https://ci.nodejs.org/job/node-test-commit/2569/

[bnoordhuis]

LGTM and sorry for the delay. Snapshotting on the armv8 bot still fails with a segmentation fault. I can probably figure out why if someone from @nodejs/build gives me access.

Rubber-stamp LGTM

@bnoordhuis I'll be slightly afk today (saturday) but ping me on irc and tell me where you need access. I'll hook you up.

[jbergstroem]

@bnoordhuis ping re access

[bnoordhuis]

@jbergstroem Sorry, must've missed your previous reply. I'll ping you on IRC later today.

[targos]

I will be on a Greek island for the next two weeks and I don't think I'll have time to play with a computer, so anyone feel free to take over this PR !

[ofrobots]

I can help with this. Enjoy your trip!

@jbergstroem I will ping you on Monday to get access to an ARM8 machine to diagnose the snapshot issue.

I updated my copy of vee-eight-5.0 (https://github.com/ofrobots/node/tree/vee-eight-5.0) to the latest 5.0-lkgr and launched a new CI: https://ci.nodejs.org/job/node-test-commit/2715/.

The snapshot generation segfault is gone (probably because of this fix). There is different failure on arm that I need to investigate.

Second CI run: https://ci.nodejs.org/job/node-test-commit/2717/. Failure seems to be a flake.

I just tried the build on the latest of this branch and am seeing the following:

$ ./node -p "process.versions"
{ http_parser: '2.6.2
node: '6.0.0-pre',
v8: '4.9.385.27',
uv: '1.8.0',
zlib: '1.2.8',
ares: '1.10.1-DEV',
modules: '47',
openssl: '1.0.2g' }

Can anyone else confirm that v8: '4.9.385.27' is showing up for them?

EDIT: nm me. Confused my branches.

@trevnorris A blank vee-eight-5.0 branch was created by @targos so that he could target this PR to that branch. Nothing has landed on that branch yet. If you want to play with V8 5.0, you'll have to add-in commits from this PR, or better, use my branch here: https://github.com/ofrobots/node/tree/vee-eight-5.0.

Taking this PR over in #5945.
