> Size_t demotion warnings on Windows x64 builds
> ----------------------------------------------
>
> Key: QPID-3038
> URL: https://issues.apache.org/jira/browse/QPID-3038
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Broker, C++ Client, C++ Clustering
> Affects Versions: 0.8
> Environment: C++ build for x64 windows platform
> Reporter: Chuck Rolke
> Priority: Minor
>
> Scattered throughout the C++ source code are headers and source modules that
> treat size_t as int32_t, uint32_t, int, ULONG, and so on. Since the warnings
> are in .H files they are repeated dozens of times in any given build. I don't
> see any of the same warnings on a 64-bit linux build. Are they suppressed? Is
> this anything to worry about? None of the instances I've seen has any real
> problem until a buffer or I/O size gets up to around 2GB so they don't seem
> that bad.
