Package atomicalign defines an Analyzer that checks for non-64-bit-aligned arguments to sync/atomic functions. On non-32-bit platforms, those functions panic if their argument variables are not 64-bit aligned. It is therefore the caller's responsibility to arrange for 64-bit alignment of such variables. See https://golang.org/pkg/sync/atomic/#pkg-note-BUG
