--- Comment #3 from Richard Smith <richard-llvm at metafoo.co.uk> ---
Clang is correct. Only odr-used variables need to be captured. Naming a
reference initialized by a constant expression does not constitute an odr-use.

See
http://wiki.edg.com/pub/Wg21albuquerque/CoreWorkingGroup/cwg_defects.html#1472
which introduced the "references initialized by constant expressions don't need
to be captured" rule.
