Thanks for your caution. Then is there a way to know that a certain
variable is aligned properly? Will the compiler make the global variable
`var p *int` in my sample code aligned properly?

Is the size of a pointer value 32 bits or 64 bits in golang when build with
`GOARCH=amd64` option specified and running on 64-bit OS?
If it's 64-bit size, is a global pointer value 8-byte aligned in memory so
that a read or write operation of that pointer value is carried out
atomically?
For exa
