Definitely not infra, speculating graphics, but you may want a project specific component...

Comment 5 by egemih@chromium.org, Oct 25 2017

Duplicate of crbug.com/663490, which is marked as WontFix at the moment. I agree with comment#3 that this is gpu related. But this is not really a bug, as much as it is an extreme corner case with the gpu taking a little longer than it should drawing a frame and the watchdog thinking there is a timeout. 
This is the link to the identical crash report: 
https://crash.corp.google.com/browse?q=product.name%3D%27Chrome_ChromeOS%27%20AND%20crash.Address%3D0%20AND%20custom_data.ChromeCrashProto.ptype%3D%27gpu-process%27&sql_dialect=googlesql&ignore_case=false&enable_rewrite=true&omit_field_name=&omit_field_value=&omit_field_opt=%3D&stbtiq=&reportid=d7587cb800156ea7&index=34#0. 
I am also attaching the stackwalk I gathered from comment#2 on this thread, which shows the almost identical stacktrace at the moment of crash. 
There is not much to do at this point but keep an eye out to see how often we see this. But it seems like it's really rare. The crash report I linked to refers to this segfault as "longstanding unavoidable crash."
