Writing a c compiler that generates MASM and uses ml64 to assemble and link. I read a lot about the x64 windows calling convention and it seemed that I did not have to add all the SEH plumbing, in that case anything I called or anything that called me would just die in the case of a machine exception . which I am fine with. I tried a few things and it seemed to work fine.

But I just had something fail on a push instruction when the stack got big. I am wondering if this is due to a stack overflow , which should cause my stack to extend (The stack isnt huge, 1.5k, so I have not hit a real stack overflow, maybe a new page is needed?)
