[jira] [Created] (MESOS-3330) Investigate ThreadSanitizer errors

Neil Conway created MESOS-3330:
----------------------------------

             Summary: Investigate ThreadSanitizer errors
                 Key: MESOS-3330
                 URL: https://issues.apache.org/jira/browse/MESOS-3330
             Project: Mesos
          Issue Type: Bug
            Reporter: Neil Conway
            Assignee: Neil Conway


Running ThreadSanitizer (http://clang.llvm.org/docs/ThreadSanitizer.html) over "make check" yields ~262 warnings/errors (data races, use-after-free, and similar).

Notes on running tsan:
* CXXFLAGS="-fsanitize=thread" LDFLAGS="-fsanitize=thread"
* This creates an additional thread, which breaks a few (fragile) tests; will be reported separately
* I ran into some problems using tsan w/ GCC 4.9; using clang 3.6 worked fine.
