This is a false positive in -Wuninitialized that can be worked around by
compiling with -O2. Please do that rather than compiling with -Og.
Thanks Jeff for your respond!
Hi Khem,
If so, do we need to just to add some logic as DEBUG_OPTIMIZATION_append
= " -Wno-error" for gcc-sanitizers to avoid -Og indicating the
-Werror=maybe-uninitialized message?
Thanks,
jeff
