Hi Felipe, The reason the code should never reach the point you indicate is because the which_ index of the variant should always be valid, and so it should always be the case that the other specialization of visitation_impl finds a match. If this is not happening, which appears to be the case, it may be due to memory corruption that is overwriting the which_ field of the variant, or it may be due to a bug in the variant code. Without more detail from you about your problem though, I won't be able to help more. Regards, Eric Felipe Magno de Almeida wrote:
Hi!
I'm having an assertion failure at visition_impl.hpp:201 But the assertion doesnt state what could be wrong, there's only a comment saying: // should never be here at runtime:
Here is the function that is being called, that shouldnt...
template < typename W, typename S , typename Visitor, typename VPCV , typename NBF > inline BOOST_VARIANT_AUX_GENERIC_RESULT_TYPE(typename Visitor::result_type) visitation_impl( int, int, Visitor&, VPCV , mpl::true_ // is_apply_visitor_unrolled , NBF, W* = 0, S* = 0 ) { // should never be here at runtime: BOOST_ASSERT(false); typedef typename Visitor::result_type result_type; return ::boost::detail::variant::forced_return< result_type >(); }
Could anyone help me? Thanks in advance,
