TypeScript Version: 3.3.0-dev.20190108

Search Terms: noimplicitany infer code fix codefix token end is child end

Code

function wrap(arr) {
  arr.sort(function (a: number, b: number) { return a < b ? -1 : 1 })
}

Expected behavior:

--noImplicitAny suggested fix on the arr parameter shouldn't crash.

There is no crash if you remove the function passed to .sort.

Actual behavior:

Error: Debug Failure. False expression: Token end is child end
