Subject: test case against union aliasing

Hi!

It seems we have some code in kernel which utilizes (rightlessly for
now) union aliasing.

So, can we create a test case against such? (Three steps: a) replace
union by struct keyword in data type in question, b) compile, c) run in
Qemu with proper functional test)

Does it make any sense?
