Hi,

BOOST_STATIC_ASSERT has different behavior on different platforms

Boost 1.34

-------- File foo01. cpp --------
#include <boost/static_assert.hpp>

struct Foo
{
            int m_value;
            Foo();
};

Foo::Foo()
{
            BOOST_STATIC_ASSERT(sizeof(this->m_value) == 4);
}

int main()
{
            Foo f;

            return 0;
}
