--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
I don't think that this is related to the implementation of unique_ptr, instead
my guess is that gcc currently does not yet implement
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#5
The code compiles well, if the destination object is not a const object or if
the initialization is direct-initialization. Before CWG 5 was reolved, it was
unclear whether the wording in 8.5 p17 (The bullet starting with: "If the
destination type is a (possibly cv-qualified) class type") was referring to a
destination type including or without it's cv qualification.
More evidence to that assumption is that the CWG 5 code example is currently
rejected by gcc as it would be expected to happen according to the "including
the cv-qualifier" interpretation.

Fixed on trunk currently. Is this important to get into 4.9?
