Exactly the same code and the same compiler options give the following results for me:
object.Exception: Test ---------------- 00 extern (C) int rt.dmain2.main(int, char**) . void runMain() . 01 extern (C) int rt.dmain2.main(int, char**) . void runAll() . 02 main 03 mainCRTStartup 04 BaseThreadInitThunk 05 RtlInitializeExceptionChain 06 RtlInitializeExceptionChain Can you please check which version of dbghelp.dll is installed on your system? Which exact version of XP do you use? (service pack, x86/x64)? Kind Regards Benjamin Thaut
