This can reproduced with a smaller program:
package main
function main() {
switch i := (interface{})(0); i.(type) {
case [0]string:
}
}

--- Comment #2 from Dmitry Vyukov <dvyukov at google dot com> ---
Chris, when you fix these, please also add tests to the main Go repo. These are
code patterns that we never saw before. Collections of these patterns will be a
great asset for regression testing and any future Go compilers.

I plan to add the test cases that GoSmith uncovered once the remaining GoSmith
issues are resolved since it's possible some of them might overlap.
