Andrew Stitcher commented on QPID-4734:
---------------------------------------
I concluded that turning the warning off completely would be a very bad idea,
as this warning is usually reliable and useful.
So I need the change that makes the minimal change that allows the build to
complete.
I decided to use a #pragma only in the affected file to change this warning so
that it doesn't cause the build to fail. This is surrounded by conditional
compilation so that it is only turned on in the specific compiler and version.
So the warning is still active and reported, but won't cause a build failure.

> Key: QPID-4734
> URL: https://issues.apache.org/jira/browse/QPID-4734
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: 0.21, 0.22, 0.23
> Environment: gcc 4.4.7 and boost 1.41 on RHEL 6
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher

> build fails with warnings turned to errors when compiling SocketTransport.cpp:
> These are potentially uninitialised variable warnings in boost::bind and
> boost::function templates and so the underlying code can't be changed by us.
> It appears that the cause here is either (or some combination):
> * The compiler's flow analysis is incorrect.
> * The compiler misinterprets the warning as being in the location that the
> template instantiation happened (our code) and so ignores the
> -Wno-system-headers flag which should stop it reporting warnings in the
> system headers.
> * There is an issue in the boost code.
> In any of these cases there is little that we can do except suppress the
> warning.
