Can not build with -race

[tp]

go build -race main.go returns

src/github.com/jmoiron/sqlx/sqlx.go:350: cannot take the address of runtime.assertE2T(runtime.typ·2 = &type."".Stmt, runtime.iface·3 = stmt).Stmt

on projects using sqlx.

Just a note to myself, this also happens building sqlx w/ -race

This builds in tip but not in go1.1.1. It's likely a bug in the race detector code which has been fixed since 1.1.1's release.
