Nobody is using cgo, it's the system DLLs which get loaded in the middle of the address space. This is very very unusual, Windows tries hard to avoid such things. It could be solved by making the initial virtual address space reservation in the PE header, not requesting it in the initialization path, that would always work, even with cgo.
