Replace buf := [HUGE_CONST]*T)(unsafe.Pointer(p))[:] with buf := [HUGE_CONST]*T)(unsafe.Pointer(p))[:n:n] Pointer p points to n of T elements. New unsafe pointer conversion logic verifies that both first and last elements point into the same Go variable. And this change adjusts all code to comply with this rule. Verified by running go test -a -short -gcflags=all=-d=checkptr crypto/x509 The test does not fail even with original version of this code. I suspect it is because all variables I changed live outside of Go memory. But I am just guessing, I don't really know how pointer checker works.
