[boost] [static_assert] Regression with gcc 3.4.2?

#include <boost/static_assert.hpp> template <typename T> struct foo { void bar(void) { BOOST_STATIC_ASSERT(false); } }; int main(void) { } --------------------------------------------------------------------- toot.cpp: In member function `void foo<T>::bar()': toot.cpp:8: error: invalid application of `sizeof' to incomplete type `boost::STATIC_ASSERTION_FAILURE< false>' --------------------------------------------------------------------- Is gcc wrong, or am I missing something really obvious? This used to work. And yes, I have the latest boost CVS snapshot. Dave
