It came up when we chatted on Monday and I had some non-determinism when dealing with one of the bug recently. It was like 1 in 10 thing so I was able to work around it but we spent a little bit of time looking at all the places we used std::set and std::map and there are a several of them. He felt it was a good build czar side project and I agreed. > > I don’t think there’s a great way to detect this automatically, but I’m happy > to hear because I was bitten by the problem several times. > I guess my question was more motivated by the curiosity than anything else. > Good work. > > — > D > _______________________________________________ > lldb-commits mailing list > lldb-commits@lists.llvm.org > https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
