While investigating this test failure.. http://www.meta-comm.com/engineering/boost-regression/cvs-head/developer/out... http://tinyurl.com/93yz9 Which is a compile-fail test, but compiles successfully with CW-8.3. I narrowed the problem down to this minimal test.. #include <boost/static_assert.hpp> template <std::size_t N> void foo_p() { BOOST_STATIC_ASSERT(N < 3); } int main() { foo_p<5>(); } ..Which compiles without problems. The static_assert code is simple enough so I'm somewhat at a loss here. Don't know how many other tests this affects but it seems kind of important to fix this. So any ideas on what sort of feature/bug this is hitting would be appreciated ;-) -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - Grafik/jabber.org
