The 64 bit version of _image_optional_header has no member BaseOfData
. See MSDN:
https://docs.microsoft.com/en-us/windows/win32/api/winnt/ns-winnt-image_optional_header64
So this is correct, it is not a bug
.
You can not add it like the 32 bit version. It is an OS provided structure and your application will probably crash! if you add it to 64 since the field order and size become invalid/

Specialize a type, not a var.

Data probably has no base in 64-bit since it is position independent, and thus linked to baseofcode.
