Well, maybe I'm missing something but I can't any see code in GCC for generating prologues, epilogues and unwind tables in the format required by the Windows x64 ABI. http://msdn.microsoft.com/en-us/library/tawsa7cb.aspx >I am a bit curious, as I found that the unwind mechanism of Windows >itself working quite well on gcc compiled code, so I assumed, that the >most important parts of its calling convention are implemented. How exactly are you testing this? Without SEH support Windows wouldn't ordinarily ever need to unwind through GCC compiled code. I assumed that's why it was never implemented. Ross Ridge
