Per the Microsoft PE/COFF document, relocation type IMAGE_REL_AMD64_SECTION means "The 16-bit section index of the section that contains the target. This is used to support debugging information."
Normally this would be assumed to be 0-based, but a symbol section number in a PE file is 1-based. Should the section index for IMAGE_REL_AMD64_SECTION relocation be written as 0 or 1 based?
