The old rethinkdb database had a ticket with this bug and there was a proposed patch. But the old issues database has gone. rethinkdb/rethinkdb#5757

[asakatida]

rethinkdb/rethinkdb#5757 there are a few fixes in there. Some of them even made it into the codebase. At the end there is discussion of Duktape, which we have implemented the patch for. That would fix this issue for next. The other proposed solution was mandating CXX=clang++, as this is clearly a bug in gcc5.
