This appears to be not a regression, since according to the standard, 
Foo::bar() indeed should be called: 

5.2.5 - Class member access [expr.ref]

-1- A postfix expression followed by a dot . or an arrow ->, optionally followed by 
the keyword template (temp.arg.explicit), and then followed by an id-expression, 
is a postfix expression. The postfix expression before the dot or arrow is evaluated;

[Footnote: This evaluation happens even if the result is unnecessary to determine 
the value of the entire postfix expression, for example if the id-expression denotes 
a static member. --- end foonote]

the result of that evaluation, together with the id-expression, determine the result 
of the entire postfix expression.
