Hi, I'm experiencing a memory leak while using lexical_cast with VC8. The leak was detected by an end-user in a long-running application and evidenced with GlowCode (a leak detection tool). The origin seems to be an allocation inside ios_base (<xiosbase>). Source code for the test: #include <string> #include <boost/lexical_cast.hpp> int main() { std::string s = "1234"; unsigned u = boost::lexical_cast<unsigned>(s); } GlowCode trace: Handle 0x1555308 (0x1555308 = HeapAlloc( 0x310000, 0x0, 40)) caller(1): malloc_base(); + 236 bytes; module MSVCR80D.dll; 0x1024DB9C caller(2): malloc_dbg(); + 725 bytes; module MSVCR80D.dll; 0x1020FAA5 caller(3): malloc_dbg(); + 105 bytes; module MSVCR80D.dll; 0x1020F839 caller(4): malloc_dbg(); + 31 bytes; module MSVCR80D.dll; 0x1020F7EF caller(5): operator new(); + 30 bytes; module MSVCP80D.dll; 0x104F938E caller(6): std::ios_base::_Init(); + 112 bytes; module MSVCP80D.dll; 0x104877B0 caller(7): std::basic_ios<char,std::char_traits<char> >::init(); + 15 bytes; module MSVCP80D.dll; 0x10497CFF caller(8): std::basic_istream<char,std::char_traits<char> line 134 + 81 bytes; module mleak.exe; 0x411A41 caller(12): boost::lexical_cast<unsigned int,std::basic_string<char,std::char_traits<char>,std::allocator<char> line 219 + 11 bytes; module mleak.exe; 0x4116BF caller(13): main(); file e:\projects\mleak\mleak.cpp; line 7 + 9 bytes; module mleak.exe; 0x41159E caller(14): __tmainCRTStartup(); file f:\rtm\vctools\crt_bld\self_x86\crt\src\crtexe.c; line 586 + 25 bytes; module mleak.exe; 0x412EA6 caller(15): mainCRTStartup(); file f:\rtm\vctools\crt_bld\self_x86\crt\src\crtexe.c; line 403, module mleak.exe; 0x412CED Regards, Josue Gomes
