Here is another report:

and I believe it's one of these crashes:

jshin@, can you look into these?

We're seeing a lot of feedback reports from users about this on elm (acer chromebook 13)

and many more.

I think there are > 50 feedback reports submitted to https://groups.google.com/a/google.com/forum/#!forum/elm-feedback-reports in the past week alone on this.

Upping the priority.

Adding the M69 and M70 TPMs

govind@ and abdulsyed@ - can you please help find an appropriate owner? We're seeing a lot of reports from users.

This crash is reported on Chrome OS, so adding Chrome OS M69 and M70 TPMs( cindyb@ & geohsu@).

+djkurtz, dianders since we're seeing this primarily on oak/veyron/gru devices

Dan/Doug, can you help narrow this down so we can find an owner to fix this? We're seeing quite a few reports every day.

@#8 - From crash stats, it looks like it is the crash is *not* on veyron, and just on oak [elm, hana] & gru [kevin, dru] (ie, our arm64 boards).  This arch dependency makes me suspect V8.

https://crash.corp.google.com/browse?q=product_name%3D%27Chrome_ChromeOS%27+AND++expanded_custom_data.ChromeCrashProto.magic_signature_1.name%3D%27icu_62%3A%3AUnicodeSet%3A%3AUnicodeSet%27#-propertyselector,-productname:1000,-magicsignature:50,-directory,-magicsignature2:50,-stablesignature:50,-clientid,devicemodel,url,-country,-magicsignaturesorted:50

It was introduced sometime before 69.0.3497.58.

A wild guess could be this CL [0], but I don't know an easy way to figure out in which (R69) Chrome OS version it landed:
https://chromium.googlesource.com/chromium/deps/icu/+/297a4dd02b9d36c92ab9b4f121e433c9c3bc14f8

The CL referred actually fixed a crash by providing correct alignment otherwise Chrome didn't even reach login screen.

Based on https://unicode-org.atlassian.net/browse/ICU-20001, more places needed a similar fix, not sure if that was done or not in Chrome 69.

Re:#9 - https://listnr.corp.google.com/product/208/report/85717555903 was on veyron_minnie, but maybe that's a different crash?

strange, this is on gnawty: https://listnr.corp.google.com/product/208/report/85713349272

But yes, the vast majority of issues are on gru and oak

gnawty and veyron may be one-offs that are unrelated

If you believe V8 might be the cause, please add the JavaScript component. Infra>V8 is for V8's infrastructure only.

cindyb@ and geohsu@ - can you please help find an owner for this? we are seeing lots of user complaints here

This issue is a dupe of bug 896322.
