Comment #5 on issue 6418 by cr...@chromium.org: Chrome: Crash Report -  
Stack Signature: -487E8E
http://code.google.com/p/chromium/issues/detail?id=6418

A few notes as I look into this...

The crash is happening on the process()->Init() call, likely on the  
reference to
process_.  I don't think it's because process_ is null, though.  It's more  
likely
that the RenderViewHost has been deleted before this call gets made.

I say that because it doesn't look possible for process_ member to be  
null.  It gets
assigned in the RenderViewHost constructor, using SiteInstance::GetProcess  
(which
should never return null, and doesn't look like it can).  There's also no  
code that
assigns to process_ outside of that.  Also, the access exception is at  
0x20, not 0x0,
so it's likely that the RenderViewHost object has been freed.

Also worth noting that there are many similar crashes reported for 0.158  
and 0.159,
all happening on the same line of RenderViewHost::CreateRenderView, but with
different stack traces leading up to it.

I'm not sure yet what would cause the RenderViewHost to be deleted first  
(or even
that this is definitely the explanation), but it seems likely.  Any ideas?
