If anybody is interested, grab the code and try it with your favorite compiler and let me know how it works out. If it doesn't compile, try #defining BOOST_FOREACH_NO_CONST_RVALUE_DETECTION and see if that fixes the problem.
Here are some results (the line numbers don't match your source because I pasted the code into a test file, but the output should still be clear) - VC8.0 (beta) crashes without BOOST_FOREACH_NO_CONST_RVALUE_DETECTION defined - Comeau 4.3.3 gives two warning and an internal error regardless of whether the defect macro is defined (see end off message) - Intel 8.0 gives lots of warnings and an internal error without the defect macro, but works fine with the defect macro defined (see end off message) Jonathan ---------------------------------------------------------------- Comeau 4.3.3 compiler output with or without defect macro "C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp", line 544: warning: use of "=" where "==" may have been intended BOOST_FOREACH( T const &t, list_of_T ) ^ "C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp", line 559: warning: use of "=" where "==" may have been intended BOOST_FOREACH( int &i, int_list ) ^ "C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp", line 569: internal err or: assertion failed: add_to_destructions_list: object lifetime and dynamic init in different memory regions (il.c, line 12018) BOOST_FOREACH( int const &i, list<int>(5,5) ) ^ ---------------------------------------------- Intel 8.0 compiler output without defect macro: C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(559): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int &i, int_list ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(569): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int const &i, list<int>(5,5) ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(142): error: function ret urning array is not allowed operator U () ^ detected during instantiation of "boost::for_each::rvalue_probe::opera tor T" based on template argument <int [3]> at line 577 C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(577): internal error: ass ertion failed at: "shared/edgcpfe/exprutil.c", line 8947 BOOST_FOREACH( int &i, int_array ) ^ compilation aborted for C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp ( code 4) ---------------------------------------------- Intel 8.0 compiler output with defect macro: C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(559): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int &i, int_list ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(569): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int const &i, list<int>(5,5) ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(577): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int &i, int_array ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(583): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int i, int_array ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(592): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( char &ch, str ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(599): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( char ch, str ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(610): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( char const &ch, sz ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(621): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int &i, ::boost::for_each::in_range( begin, end ) ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(629): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int i, iter_pair ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(636): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int i, rvalue_list() ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(644): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( int i, const_rvalue_list() ) ^ C:\DOCUME~1\turkanis\Home\C++\overloadvc71\example.cpp(544): warning #187: use o f "=" where "==" may have been intended BOOST_FOREACH( T const &t, list_of_T ) ^ detected during instantiation of "void baz(const std::list<T, std::all ocator<_Elem>> &) [with T=int]"
