Mukund, If you suspect a bug in the compiler or the standard library, compile annd run the program using the latest version or, even better, tip so that you include all known bug fixes.
I couldn't reproduce your error at Go tip: $ go version go version devel +bebfd4b Tue Apr 4 06:26:11 2017 +0000 linux/amd64 $ go run mukund.go $ go run -race mukund.go $ Using the line number, math/rand/rng.go:243, I backtracked to your likely version. I couldn't reproduce your error at go1.7: $ go version go version go1.7.5 linux/amd64 $ go run mukund.go $ go run -race mukund.go $ I couldn't reproduce your error going as far back as go1.4: $ go version go version go1.4-bootstrap-20161024 linux/amd64 $ go run mukund.go $ go run -race mukund.go $ mukund.go: https://play.golang.org/p/SGkJyxYPiR To help you further, we need you to provide us with a small program which we can use to reproduce your error. Also, provide us with the output from the go version and go env commands.
