Looks like a show stoping bug in the 20050913 prerelease. The failing case can
be simplified to:
struct a_class {
public:
static const unsigned complexity = 0;
};
template <class T>
struct a_template_class {
public:
static const unsigned complexity = 0;
};
void gcc_402_problem()
{
BOOST_STATIC_ASSERT (a_class::complexity == 0); // OK
BOOST_STATIC_ASSERT (a_template_class<int>::complexity == 0); // FAILS!
}
This probably breaks a great deal of Boost!
GCC shows a bug fixed on and before 2005-9-12
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23691
which is very similar.
