Second argument of servicemain is a pointer. See https://msdn.microsoft.com/en-us/library/windows/desktop/ms685138(v=vs.85).aspx So amd64 assembler code should use MOVQ to read that value. I probably copied 386 assembler code into amd64 and did not adjust the code. Broken code was used to pass parameters to the service, so add some tests to verify that parameter passing works.
