Invalid conversions of 'uintptr' to 'unsafe.Pointer'

Reports possibly incorrect conversions of uintptr to unsafe.Pointer.

A conversion from uintptr to unsafe.Pointer is invalid if it implies that there is a uintptr-typed word in memory that holds a pointer value, because that word will be invisible to stack copying and to the garbage collector.

Example of invalid usage:

nums := []int8{42, 24}
ptr := unsafe.Pointer(&nums[0])
addr := uintptr(ptr) // address is stored to a local variable
ptr = unsafe.Pointer(addr + uintptr(1))

Example of valid usage:

nums := []int8{42, 24}
ptr := unsafe.Pointer(&nums[0])
ptr = unsafe.Pointer(uintptr(ptr) + uintptr(1))
