I hit a similar issue on intel platform since updating meta-browser. It 
wasn't crashing, but was getting the 'Aw, Snap' chromium page on any 
html5 video or audio.
It turned out to be because the ffmpeg codecs have been separated into 
their own split package.
Adding both 'chromium' and 'chromium-codecs-ffmpeg' to the IMAGE_INSTALL 
resolved the issue for me.
Possibly not the same issue, but sounds similar.
Cheers,
Mik.

This means exactly that the browser tab has crashed (it resides in a
separate sandboxed process).

Well, I found additional issues with Chromium, so it seems important to
really analyze the crash. I don't think me or someone else will be able
to fix the issue by just moving libs around, without understanding the
problem (Chromium is now almost 17M LOCS, not good for guessing).

Adding openembedded guys in the loop.

Do you have a crash log? If not, you should change your build from Release
to Debug and
get some backtraces.

The chromium debug binary is 3.1GiB, there's no way to run this on my
ARM target. If you have other suggestions how to extract trace/debug
info, I would be glad to try them.

Commit 30b8d6b3d0d6501c56ef6967a2fa73a3d4bf5fe9 is the last known good
commit. After it the component either doesn't compile, libs are missing
or video tag isn't working.

Looks like it's a "revert time" for the customer builds...

I'll try to create crash dumps later. For now git bisect was the
fastest way to deliver a working browser for the customer.

Might be packaging splitting which can have changes. One way to easily
track this is using buildhistory and compare both packaged outputs.

It looks to me like that revision updated by 2 major versions of
Chrome - more likely there are goblins in there than just a packaging
issue.

Not really. Commit 30b8d6b3d0d6501c56ef6967a2fa73a3d4bf5fe9 is working
OK, as I described. Issues start from the next commit,
355f6d474462996c3bf07d7a72233b6c81cb2e8a.

Ah, I should have read your comment more thoroughly.  Indeed the next
commit (355f6d) is quite intrusive - it's easy to see that something
might have been missed in that split of the recipes.

Is this problem only on i.MX6?  Have you tried it on other ARM targets
or even PC?

No, I haven't tried it elsewhere. My usual motivation to avoid that is
because there are tons of possible differences (toolchains, libs, cpu
architectures, kernels, patch sets to fix SoC issues) and it's next to
impossible to guarantee that the code and data have precisely the same
layout in memory, and that the code is executed precisely the same way.

But this is my perception, it's entirely OK if others see things in
different perspective :D.

Kind regards,
Nikolay
