More of a test balloon that a real report as you alluded to.
I was wondering if it's just me, and from your response it seems 
to be just me.

I did more digging and with newer compilers I don't see the issue
either. So I did:

  ./tools/testing/kunit/kunit.py run --alltests --json --arch=x86_64 \
	 --kconfig_add CONFIG_INIT_STACK_ALL_ZERO=n 

And the problem reproduces on recent compilers, too. Which leads me
to thinking that the tests are broken but stack init covers it up.. ?
Strangely tho

	make W=1 LLVM=1 ...

doesn't report any uninitialized variable warnings.
