Epic Wasm applications broken

Project Member Reported by aseemgarg@chromium.org, Nov 21 2017

Issue description

The following Epic applications do not finish on "Compiling WebAssembly" step:

Zen Garden: https://s3.amazonaws.com/mozilla-games/ZenGarden/EpicZenGarden.html

Sun Temple: https://s3.amazonaws.com/mozilla-games/tmp/2017-02-21-SunTemple/SunTemple.html

StylizedRenderer: https://s3.amazonaws.com/mozilla-games/tmp/2017-02-21-StylizedRendering/StylizedRendering.html

PlatformerGame: https://s3.amazonaws.com/mozilla-games/tmp/2017-02-21-PlatformerGame/PlatformerGame.html

Steps to reproduce:
1. Build chrome at head
2. Open any of the benchmarks

The issue seems to affect all platforms except Mac. It seems the applications were working earlier and have regressed recently.

Did you try disabling async compilation (--js-flags=--nowasm-async-compilation)?

Comment 2 by ahaas@chromium.org, Nov 21 2017

Hi Aseem,
I cannot reproduce this issue locally. What are the GN args you used to build Chrome?
I cannot reproduce the issue neither with chrome nor the content_shell. I tried with and without async compilation. I used the following GN args:
enable_nacl = false
is_debug = false
use_goma = true
Cheers, Andreas

It seems this did get fixed sometime over the weekend or yesterday. Working today for me too.
Zen Garden still problematic for me but that might be due to me being on remote desktop. Will close the bug after verifying tomorrow.

I think it could be interesting to figure out what caused this regression, and what fixed it. Could you run a bisection?
Status: WontFix (was: Untriaged)
Can't reproduce this anymore. Went back all the way to Thursday and checked out a commit that failed in try jobs (I was trying to add Epic Zen Garden in telemetry) but it is successfully working locally for me. Closing the bug.
