Track 51+ as topcrash. Hi :kanru, Can you help shed some light here?

This is a crash entirely within Flash code. I doubt having a Mozilla engineering spend time on it would be fruitful. It's interesting that symsrv.dll is on the stack; that's pretty unusual and indicates some kind of developer mode I think. Need to figure out whether all of these crashes are strncmp/TargetInternetOpenA/F213.../symsrv or whether there are other patterns. It may be that *this* new regression is from 22.214.171.124 and previous builds have other lower-volume crashes which also happen to be strncmp. Probably also worth adding strcmp to the appendlist, since it's by definition not interesting by itself. I filed bug 1321288 for that.
I verified that this is all TargetInternetOpenA. It appears that symsrv.dll may be a virus, and there's also dlcoer.dll loaded in some of these reports which is a known virus. Unless you think it's valuable to try and notify these users to run a virus removal tool, I think we should INCOMPLETE this.
> Unless you think it's valuable to try and notify these users to run a virus removal tool It looks like a few of them provided an email address, so I guess we could try sending a mail to inform them. Then again, I suppose it's hard to avoid making that message just look like regular spam with links to "virus removal" tools... so it's probably not worth the effort.
