Confirmed. Happens with optimization levels -O0 and -Os, but not -O1, -O2, -O3,
-Og, or -Ofast.

There is another bug about a similar thing but with
constructors/deconstructors.
-finstrument-functions inserts try/finally blocks in the code and the dead code
is not removed before hand so the warning mechanism gets confused.
