No, it's the lame warning-for-uninitialized-memory (your variables are
address-taken) code that triggered in 4.4 but not in newer releases.
Thus it's more related to PR50040.

Note that I don't think we should warn for bitwise OR with 1 (but we should for
bitwise AND), the testcase will simply make one bit initialized, not
using any uninitialized info.  Thus not warning for this particular case is
good.
