[jira] [Created] (MESOS-2925) Invalid usage of ATOMIC_FLAG_INIT in member initialization

Paul Brett created MESOS-2925:
---------------------------------

             Summary: Invalid usage of ATOMIC_FLAG_INIT in member initialization
                 Key: MESOS-2925
                 URL: https://issues.apache.org/jira/browse/MESOS-2925
             Project: Mesos
          Issue Type: Bug
          Components: libprocess
    Affects Versions: 0.23.0
            Reporter: Paul Brett


The C++ specification states:

The macro ATOMIC_FLAG_INIT shall be defined in such a way that it can be used to initialize an object of type atomic_flag to the clear state. The macro can be used in the form: "atomic_flag guard = ATOMIC_FLAG_INIT; "It is unspecified whether the macro can be used in other initialization contexts." 

Clang catches this (although reports it erroneously as a braced scaled init issue) and refuses to compile libprocess.
