I think this is related to issue #4019. I can still reproduce the problem in tip, though
the line number is now off by 1 instead of 2 (in this particular example).

What steps will reproduce the problem?
Run 'go build test.go' (attached).

To see the desired behavior, run 'gcc -Wall -lcrypto test.c'.

What is the expected output?
# command-line-arguments
cc1: warnings being treated as errors
test.go: In function 'test':
test.go:8: warning: value computed is not used

What do you see instead?
# command-line-arguments
cc1: warnings being treated as errors
test.go: In function 'test':
test.go:7: warning: value computed is not used

Which compiler are you using (5g, 6g, 8g, gccgo)?
6g

Which operating system are you using?
FreeBSD 9.0-RELEASE-p5 amd64

Which version are you using?  (run 'go version')
go version devel +b3017cc3e17b Wed Apr 10 21:41:54 2013 -0700 freebsd/amd64
