Created attachment 717836 [details] trace During Firefox start-up with ThreadSanitizer (LLVM version), we get a data race reported as described in the attached log. Trace was created on mozilla-central with changeset c233837cce08. According to the TSan devs, most of the reported traces should be real data races, even though they can be "benign". We need to determine if the race can/should be fixed, or put on the ignore list. Even for benign races, TSan devs suggest to fix them (second priority), as they can also cause problems .  http://software.intel.com/en-us/blogs/2013/01/06/benign-data-races-what-could-possibly-go-wrong
This could be a bug in networking stuff, given that #6 nsStreamTransportService::Init() netwerk/base/src/nsStreamTransportService.cpp:441 (libxul.so+0x0000008b85ce) is on the stack, using xpcom. Ccing some people for networking.
This looks like the same race reported in bug 833349.
