--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> 2012-08-21 16:48:09 CDT ---
This is a defect in C++ itself:

http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#325

Clang matches the behavior of all other C++ compilers here; this is not a bug
(though depending on the way in which that issue is resolved, we may need to
revisit this).

The workaround is to add parentheses around the default argument expression.
