The following program panics when compiled using `gc`: ```Go package main func main() { x := 0 _ = 1 / x } ``` It does not panic when compiled with GopherJS. This is the same issue as https://github.com/golang/go/issues/18024 upstream, and it was uncovered by me when working on go1.8 branch thanks to https://github.com/golang/go/commit/c2bb52b8304a814b8e2b447953c3341ac31bbee8 causing `fixedbugs/issue8613.go` test to run as part of [`TestGoRepositoryCompilerTests`](https://github.com/gopherjs/gopherjs/blob/e34a5cd6a1bc7c4fde759f2d3039852fc68b5fcc/tests/gorepo_test.go#L12). Low priority, I'm reporting for tracking purposes.
