There is one already in gcc bugzilla: 18551.  It appears easy to fix,
if only the "you should not use current_function_name()" suggestion
could mention what should be used instead :)

BTW, 19329 (from the long bug list) is not yet closed probably because
it should be fixed properly outside the AVR target, by not generating
these "shift by 0" insns at all.  The AVR target now has a workaround,
but some other targets might be affected as well.
