The make_storage template at line 215 of:

uses max over the alignment_of's for the types in the variant (See line2 233-235) to calculate the variant's alignment. However, to handle the extended alignments described on page 3 of:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2165.pdf
the boost::math::static_lcm template should be used instead of max.
Excellent catch. I've created http://svn.boost.org/trac/boost/ticket/993 for this issue. The question I have now is the urgency of the fix. In particular, this issue has been in the code since the beginning but has not been reported, suggesting perhaps it has not caused problems in practice. Do you have any thoughts? Thanks, Eric
