I worked around both errors on one of the machines my just getting rid of everything `webrtc` related and starting over in this regard. We should not need to do this, though. I therefore keep the second machine as-is for debugging purposes. > > Sorry, did you mean the errors you have are reproducible or the error I mentioned in #comment:24? I can reproduce the error in comment:34 on two different machines and that's what I meant. Over the weekend I tried to look more closely at it. So, updating to mingw-w64 `master` and GCC 6.4.0 does not help. Then I tried to build clang `master` and see whether we can verify the claim in comment:25 (and maybe be lucky because our bugs got fixed like last week :) ). I tried for a while to get the clang build going by setting `LLVM_FORCE_HEAD_REVISION` to `1`. It turns out that breaks the clang plugin compilation and other clang tools' compilation as well. Not compiling those gives a proper clang based on `master`, unfortunately requires the WebRTC build those missing clang tools. I then settled to use the latest prebuilt clang binaries (by messing with the `update.py` script (see: https://chromium.googlesource.com/chromium/src/tools/clang/+/master/scripts/update.py)) using rev 332335 which is just ca. 400 commit behind the latest one. I am still getting the same errors as in comment:24. I guess it's time to look at the symbols... -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/25483#comment:37> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
