You need to read https://golang.org/pkg/unsafe/#Pointer *very, very, very*
carefully before using unsafe.Pointer in any way. It spells out 6
conversions that are considered "valid". It says: "Code not using these
patterns is likely to be invalid today or to become invalid in the future."
AFAICT, your code does not fit any of those 6 allowable patterns.
Go is simple and easy, CGO is tricky, difficult and full of dragons.
