[Issue]: Nvidia HIP runtime API returning pointer to local variable

[flg]

Problem Description

I get a number of compilation warnings when compiling for NVIDIA HIP platform.

The majority is not too worrying like these deprecated:

/opt/rocm-6.2.2/include/hip/nvidia_detail/nvidia_hip_runtime_api.h:3570:46: warning: ‘CUresult cuTexRefSetFlags(CUtexref, unsigned int)’ is deprecated [-Wdeprecated-declarations]
 3570 |     return hipCUResultTohipError(cuTexRefSetFlags(hTexRef,Flags));
      |                              ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~

Some are more concerning like these returning pointer to local variable:

/opt/rocm-6.2.2/include/hip/nvidia_detail/nvidia_hip_runtime_api.h(508): warning #1056-D: returning pointer to local variable
      return &a;
             ^

I can't imagine a context in which returning a pointer to a local variable actually makes sense.

Are those expected? Is there a work-around ? A fix ?

Thanks. Do you know when we can hope to have this included in an official release? I'm not familiar with ROCm release cycle.

@flg You can expect it in the next release.
