Hi, I compile a small test program using Visual C++ 10.0 (Visual Studio 2010 Premium) with static code analysis turned on (option /analyze): #include <boost/array.hpp> int main() { typedef int T; // short, char, etc. boost::array<T, 2> x; T a = x[0]; } and whichever integer type I use for T, the analyser throws similar reports every time: 1>------ Build started: Project: boost_array_test, Configuration: Debug Win32 ------ 1> boost_array_test.cpp 1>g:\workshop\boost\boost_test\array\boost_array_test.cpp(5): warning C4189: 'a' : local variable is initialized but not referenced 1>g:\dev\boost\_svn\trunk\boost\array.hpp(111): warning C6385: Invalid data: accessing 'elems', the readable size is '8' bytes, but '12' bytes might be read: Lines: 110, 111 1> G:\dev\boost\_svn\trunk\boost/array.hpp(109) : while compiling class template member function 'int &boost::array<T,N>::operator [](boost::array<T,N>::size_type)' 1> with 1> [ 1> T=int, 1> N=0x2 1> ] 1> boost_array_test.cpp(4) : see reference to class template instantiation 'boost::array<T,N>' being compiled 1> with 1> [ 1> T=int, 1> N=0x2 1> ] 1> boost_array_test.vcxproj -> G:\workshop\boost\boost_test\array\Debug\boost_array_test.exe ========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ========== Shall I report a ticket? No warnings are reported for the std::array provided with Visaul C++ 10.0. Best regards, -- Mateusz Loskot, http://mateusz.loskot.net
