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 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::init(); + 15 bytes; module MSVCP80D.dll; 0x10497CFF caller(8): std::basic_istream
