Thanks for reporting all these bugs with high-quality backtraces. I know we're a bit slow in getting to them all, but it's very much appreciated.

This is probably another cross-platform thread safety bug. It's not immediately clear to me what's wrong, because ResourceResponseBase and HTTPHeaderMap both seem to be pretty careful about copying all the strings before passing them across threads. If you happen to hit this one again, or if you've got it saved in coredumpctl, a 'thread apply all bt full' would be helpful.
