That you use GoAsm and GoLink instead of GCC can make a difference.
Different build toolchains may not be compatible. Where did you get your
GTK+ packages from? Does calling GTK+ functions even work?

Either way, the stack usage is probably the same for all 32-bit Windows
programs. In the MSYS2 GCC, argc is at ebp+8, argv is at ebp+12, so
argv[1] is retrieved like this:

mov    eax, DWORD PTR [ebp+12]
mov    eax, DWORD PTR [eax+4]

Maybe you accessed the argv array pointer instead of the array elements?

You can try it yourself on MSYS2 and compiling to assembler code like this

gcc `pkg-config --cflags gtk+-3.0` -S test.c -masm=intel

and linking like this:

gcc -o test test.s `pkg-config --libs gtk+-3.0`

I have no idea how to do this in GoAsm and I'm not going to try.
