cmd/go: 'go run' doesn't provide os.Stdin to the program it's running. #2875
Description
by consalus:
What steps will reproduce the problem?
1. 'go run' a program that takes input from Stdin.
2. It gets EOF, since it's run with os.DevNull as Stdin.
Which compiler are you using (5g, 6g, 8g, gccgo)?
The 'go' tool, since we no longer use the compiler directory.
But it's certainly using 6g.
Which operating system are you using?
Mac OS X 10.7.2
Which revision are you using? (hg identify)
