I'm getting the following error in library_status.cpp, which is keeping the OSL5 (C++0x) regression tester from submitting nightly regression tests. The error is in library_status.cpp, although I don't actually know what that is :) gcc.compile.c++ ../../../bin.v2/tools/regression/build/gcc-4.3.0_c+ +0x/release/link-static/library_status.o In file included from ../../../boost/function/detail/prologue.hpp:17, from ../../../boost/function.hpp:24, from ../../../boost/iterator/transform_iterator.hpp: 10, from ../library_status.cpp:34: ../../../boost/function/function_base.hpp: In member function 'const std::type_info& boost::function_base::target_type() const': ../../../boost/function/function_base.hpp:493: warning: dereferencing type-punned pointer will break strict-aliasing rules ../library_status.cpp: In constructor '<unnamed>::col_node::col_node (const std::string&)': ../library_status.cpp:92: warning: '<unnamed>::col_node::m_name' will be initialized after ../library_status.cpp:91: warning: 'bool <unnamed>::col_node::is_leaf_directory' ../library_status.cpp:95: warning: when initialized here ../library_status.cpp: In member function 'std::pair<int, int><unnamed>::col_node::get_spans()': ../library_status.cpp:117: error: passing 'const<unnamed>::col_node' as 'this' argument of 'std::pair<int, int><unnamed>::col_node::get_spans()' discards qualifiers ../library_status.cpp: In function 'void<unnamed>::build_node_tree (const boost::filesystem::path&, <unnamed>::col_node&)': ../library_status.cpp:131: error: invalid initialization of reference of type '<unnamed>::col_node&' from expression of type 'const<unnamed>::col_node' ../library_status.cpp:124: error: in passing argument 2 of 'void<unnamed>::build_node_tree(const boost::filesystem::path&, <unnamed>::col_node&)' In file included from ../../../boost/test/impl/execution_monitor.ipp:30, from ../../../boost/test/included/ prg_exec_monitor.hpp:18, from ../library_status.cpp:817: ../../../boost/test/utils/basic_cstring/basic_cstring.hpp: At global scope: ../../../boost/test/utils/basic_cstring/basic_cstring.hpp: In instantiation of 'boost::unit_test::basic_cstring<const char>': ../../../boost/test/execution_monitor.hpp:125: instantiated from here ../../../boost/test/utils/basic_cstring/basic_cstring.hpp:209: warning: type qualifiers ignored on function return type ../../../boost/test/utils/basic_cstring/basic_cstring.hpp:218: warning: type qualifiers ignored on function return type - Doug
