Resolution: Fixed
> pn_data_fill test passes uncast 0 into varargs for null pointer
> ---------------------------------------------------------------
>
> Key: PROTON-2960
> URL: https://issues.apache.org/jira/browse/PROTON-2960
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.40.0
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Priority: Major
> Fix For: proton-c-0.41.0
>
>
> In a varargs context 0 is interpreted as int never void* (or any other
> pointer type). This means that on a 64 bit machine (with the common ABIs) 0
> is only 32 bits not the full 64 of a pointer.
> This is especially visible on ARM64 under macOS, and can be hidden if it's on
> a different ABI and in the early parameters - this is due to register versus
> stack placement of parameters.
> There are some example of this error in the code testing pn_data_fill.
