LU-3404 build: fix 'incorrect expression' errors

Fix 'program hangs' defects found by Coverity version 6.5.1:
Array compared against 0 (NO_EFFECT)
Comparing an array to null is not useful.
Copy-paste error (COPY_PASTE_ERROR)
This line looks like a copy-paste error.
Self assignment (NO_EFFECT)
Assignment operation has no effect.
Side effect in assertion (ASSERT_SIDE_EFFECT)
Assignment has a side effect. This code will work differently in a
non-debug build. You might have intended to use a comparison instead.
Wrong sizeof argument (SIZEOF_MISMATCH)
Passing argument is suspicious.
