I'm trying to compile our code in an environment where we treat warnings as errors. This worked fine when we used GCC 4.1.2 which is fairly forgiving when compared to newer versions. However, after upgrading to GCC 4.4.1 (and 4.4.2) we ran into a warning in hash_table_impl.hpp in Boost 1.40.0:
.../include/boost/unordered/detail/hash_table_impl.hpp: In member function 'void boost::unordered_detail::hash_table_data_equivalent_keys<Alloc>:: node_constructor::construct_preamble() [with Alloc = std::allocator<std::pair <const unsigned int, GFL::refcounted_value<const std::basic_string<char, std:: char_traits<char>, std::allocator<char> > > > >]': .../include/boost/unordered/detail/hash_table_impl.hpp:101: error: '<anonymous>' may be used uninitialized in this function
Place could you send an example of code that triggers this warning, as I don't get it. Also, it's a bit confusing as the warning says line 101 while construct_preamble starts at line 184 so can you post the whole of the error? Daniel
