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

Which operating system are you using?
slackware linux 64 bit

Which version are you using?  (run 'go version')
go version devel +7359dad2971d Wed Jan 09 22:03:41 2013 +0100 linux/amd64

Please provide any additional information below.
for some reason other people running 64 bit hasnt been able to reproduce it. I am using
the latest kernel 3.8rc2 if that matters, otherwise, i cannot think of any software
updates ive done recently.
