Created an attachment (id=5424)
 --> (http://llvm.org/bugs/attachment.cgi?id=5424)
reduced testcase

Attached are both a preprocessed file and a reduced version that GCC is happy
to compile but Clang++ bombs with a compile error.  I'm not sure who's right
but wanted to report this.  This is from Mozilla's dev head.  Intel C++ and Sun
C++ are also happy about the reduced testcase.
