// 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
