I don't think it's variadic templates specifically, but attempting to brace-init the elements of an array.

Is this a template argument deduction error? There should be more to this message.

As a favor to Boost, I am willing to file compiler bugs for these issues, but I (and the compiler team) would like to have minimal test cases, i.e. small source files with no Boost includes. The compiler team can deal with preprocessed files but digging through tons of source takes longer.
