Wow, that's very strange. Adding a few folks who may have some clue what's going on.

Very weird. erg, ideas?

I'm pretty sure this used to work, so you might be able to bisect it.

On ToT with a debug build, I don't even get a window. I get the following stack trace:

[0620/160159.385148:FATAL:post_task.cc(72)] Check failed: TaskScheduler::GetInstance(). Ref. Prerequisite section of post_task.h

Possibly a regression due to the task scheduler change over?

Filed the bug (735971) for check failure.

Revertomg https://chromium-review.googlesource.com/524023 fixes the check failure, but the regression seemed to happen before.

tetsui@, can you run bisect?

And if you just want to see views exmaple, you can run ash_shell_with_content on cros.

Thank you for fixing the crash. I found at least in 7f9e151f4eb5356be261d478d52b8a07951108dc (Fri Jan 8 15:23:47 2016 -0800) it wasn't broken, so I'm going to bisect and detect when it was broken.

By the way, ash_shell_with_content build is also broken on ToT a50b4ecbbf6f9b304fef48c6afc7327999a13d02 because of freetype link error...
$ cros chrome-sdk --board=link
$ gn gen out_$SDK_BOARD/Release --args="$GN_ARGS"
$ ninja -C out_${SDK_BOARD}/Release -j500 -l 10  ash_shell_with_content

Thank you for your advice.

it's broken from 8eb035c0f0b18c55ddd76dad607649e596035995 ( https://crrev.com/2029323004 ), but how it's broken is different from near ToT. It's not upside down, but just an empty window is shown. I would further bisect this.

(when running gclient sync, i had to add --disable-syntax-validation -R options.)

tetsui, on tip of tree ( 6cba92dfce689e4f5911421d50c6656d8b4dc86d ) ash_shell_with_content works fine for me on a debug build on linux desktop.

views_examples_exe is upside down from 511c2ded54ef4c20b0013cf7057217c1971f3bb4 ( https://crrev.com/2661123003 ).

For now, ash_shell_with_content works for me. Thank you!
$ gn gen out/Release --args='is_debug=false use_goma=true target_os="chromeos" is_component_build=true remove_webcore_debug_symbols=true'
$ ninja -j500 -C out/Release ash_shell_with_content && out/Release/ash_shell_with_content

Un-cc-ing me from all bugs on my final day.

This bug has an owner, thus, it's been triaged. Changing status to "assigned".

Confirmed it's not fixed yet on ToT. Assigning to sky@ as it's views related.
