Comment #2 on issue 14627 by [email protected]: Crash - std::_Rb_tree<std::string, std::pair<std::string const, SdchManager::Dictionary*>, std::_Select1st<std::pair<std::string const, SdchManager::Dictionary*> >, std::less<std::string>, std::allocator<std::pair<std::string const, SdchManager::Dictionary*> > >::find(std::string const&) http://code.google.com/p/chromium/issues/detail?id=14627
Usually a problem in an STL map suggests that there is a threading problem, and the map is being changed on one thread, while being accessed on another. In this case, the dictionary map is being consulted during the start of a filtering operation, to see if the dictionary referenced in the SDCH encoded content is present. That check (and processing) is done on the IO thread. The dictionary is updated when an http request returns with a dictionary, and that too is supposed to be on the IO thread. Hence, it is hard to imagine a crash scenario. The quoted bug suggests this bug is all the way up at crasher number 25, but also says it has only appeared in only one crash report for one user... which makes me a little skeptical about the crash, and whether it is an actual problem. I just today (after 189 shipped) enabled SDCH on the mac, and hence it should not even have been active code on a Mac shipped build. The code around the SDCH filter has not been changing of recent, so it is also hard to suggest a regression in this area, other than generic problems with the network stack, and its recent refactoring. I'd like to wait-n-see if this shows up repeatedly before trying to dig much deeper. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
