--- Comment #1 from David Blaikie <dblai...@gmail.com> ---
This code (with the static member definition commented out) exhibits undefined
behavior due to an ODR use of 'foo' without a definition of 'foo'.
The "const static long long foo = 5;" (even with the "= 5") is only a
declaration of foo and must have an out of line definition (the initial value
("= 5") can remain in the declaration if you want/for various reasons).
If you want to keep the initial value inline at the declaration, then omit the
initial value in the definition (write it as "const long long Foo::foo;").
