A unreproducible crash in a one-line function (that doesn't appear to have any syscalls) in a VDSO...I'm unsure how to start investigating. I find this GN config weird: target_cpu = "x86" v8_target_cpu = "arm"

I'm redoing the task for clarity. I think [vdso] is a red herring due to clusterfuzz instrumentation (though I'm not sure *why*). I see it also in issue 708438 which is a real crasher. That being said, it not being reproducible is not a great sign.

Looking at the error, I think it is likely that this is crashing accessing network_delegate_, which is at 32 byte offset (0x20) from URLRequestContext. It is also unclear that this object will always be non-null. I couldn't find any crashers on the dashboard though. Maybe we should add a CHECK?
