[cfe-dev] Clang Static Analyzer and Strict Aliasing

Hi Cfe-dev,

I'm not particularly familiar with the clang static analzyer, so would like some help with a bug that was filed against it (when compiling for RISC-V, but I don't think that's the issue here, as the bug also shows up with the default target).

The bug is here: https://bugs.llvm.org/show_bug.cgi?id=47727 <https://bugs.llvm.org/show_bug.cgi?id=47727>

Is it expected that the static analzyer will catch (some?) strict aliasing issues like this?
