--- Comment #1 from David Blaikie <dblaikie at gmail.com> ---
"const" on member functions is very different than __attribute__((const)) for
instance, in the code below it would be entirely valid for the
Function_Attributes_const_0 member function to return a different value on each
call (eg: it could use a global variable and increment it then return the
incremented value) - so this optimization cannot be performed.

You can put __attribute__((const)) on the member function and then it should do
what you expect.
