[boost] mpl::equal<> broke on GCC4? (using 1.33 boost)

// lifted from mpl reference manul typedef mpl::vector<char,int,unsigned,long,unsigned long> s1; typedef mpl::list<char,int,unsigned,long, unsigned long> s2; // new list - nothing but floats typedef mpl::list<float,float,float,float,float> s3; void shouldnotwork() { // this one is lifted RIGHT from the example in the MPL ref manual // compiles without error (as expected) BOOST_MPL_ASSERT(( mpl::equal< s1, s2 > )); // now use s3- which is VERY different from s1 // this compiles without error on GCC4 (which is NOT expected) BOOST_MPL_ASSERT(( mpl::equal< s1, s3 > )); } Sorry I have not tested any other compilers
