I have no idea how to debug this.

I can reproduce this cross compiling from linux amd64 to linux i386 with go 1.7beta2.

This is not new, it happens with go1.6.2 too. There's an amd64 no-optimization builder, but no 368 no-optimization builder, that's probably why no one ever noticed.

@ALTree: I just tried with go1.6.2 and it doesn't crash.

To make it crash on go1.6.2, remove the -l flag, i.e. run

env GOARCH=386 go build -gcflags -N prova.go

Marking as go1.8 since this is not a regression. Hopefully moving 386 to SSA will fix this for free.

I'm unable to reproduce on HEAD from linux/amd64 to linux/386. Please comment if you think this is still an issue.
