  Version:  Boost Release Branch                  |    Severity:  Regression

--------------------------------------------------+-------------------------
 Something between [73158] and [73126] in the release branch causes the
 attached program to fail with g++-4.5 and clang-2.9 (showing the clang
 error message here).

 Trunk is fine.

 Could be an MPL issue and not a spirit issue. I think the problem already
 existed in trunk and simply was not merged yet.
