Paul Brett commented on MESOS-2925:
-----------------------------------
[~jvanremoortere] - I think the init macro in the initializer list use looks
much better but the compiler warns against it because the behavior is undefined
and therefore unsafe. BTW, I'm using clang on Linux, so I don't know if the
proposed Apple tweak would help me.
> 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.
