It would probably be valuable if you posted a crash report from the machine. It has the information that will let us confirm the availability of the symbols.

You're looking at the wrong URL. :)

http://symbols.mozilla.org/DWrite.pdb/E3514AA7ABB7433EB5E8CED252C27C101/DWrite.sym

exists. Looks like it was just picked up by the symbol fetching script last night, so you probably just missed it. The script backfills based on the list of missing symbols generated from crash-stats, so it lags a little bit.

oops

Interesting, I didn't know that we only generated symbol files for libraries that crash-stats knows about.

And we really need a button in perf.html to re-trigger symbolication.

Now that we have that symbol file, new profiles from these machines (or from this Windows version) should have proper DWrite symbols.
