My Env: cpu x86_64, windows 10, NASM 2.11.02, linking with MINGW64 GCC 4.8.1.

I am a beginer to NASM. I wants to implament a program calculate 1 add 1 and output.

I tried to call add_one function following windows's x64 calling convention by moving the first argument into rax and reserving 32 bytes of shadow storage (I actually reserved 40 bytes to align rsp to 16). This calling method works when I tried to call functions like puts. But this program abort with segmentation fault after about 1.5 seconds without outputing anything.

I'm not a native English speaker, so sorry to my grammer mistakes.
