--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Will take a look. This is ipa-pure-const bug.  We have:

{anonymous}::FooBar::_ZThn8_N12_GLOBAL__N_16FooBar3fooEv (_3);

(i.e. we now devirtualize to call to thunk) and consequently we mark:

Function found to be nothrow: virtual void
{anonymous}::FooBar::_ZThn8_N12_GLOBAL__N_16FooBar3fooEv()

I suppose ipa-pure-const is confused about same body alias wich is used to call
the virtual method.
