Re: [boost] [aligned_storage][repost] problems with GCC 4.0.0 20050309

The class aligned_storage in boost/aligned_storage.hpp has the following decl:

class aligned_storage;

GCC 4.0 complains about the default value for aligmnent_ saying that:

'(size_t)((-1))' is not a valid template argument for type 'unsigned int' because it is a non-constant expression

which is ruining some of the regression tests. Is GCC right or shall I submit a bug report at gcc.gnu.org/bugzilla?

I don't see anything in the standard or in the issue lists that prohibits size_t(-1) as an integral constant expression. Bug report.
