compiler exception: "Too many nodes written to output" #12961
Description
TypeScript Version: 2.1.4
Code
// A *self-contained* demonstration of the problem follows...
export class Test {
constructor() {
let outerArray: Array<number> = [1, 2, 3];
let innerArray: Array<number> = [1, 2, 3];
for (let outer of outerArray)
for (let inner of innerArray) {
this.aFunction((newValue, oldValue) => {
console.log(`${outer} ${inner} ${newValue}`);
});
}
}
public aFunction(func: (newValue: any, oldValue: any) => void): void {
}
}tsconfig looks like this:
{
"compilerOptions": {
"moduleResolution": "node",
"target": "es5"
},
"files": [ "test.ts" ]
}
Expected behavior:
Should compile
Actual behavior:
The typescript compiler (tsc.exe) fails on an assertion, throwing the following exception:
Error: Debug Failure. False expression: Too many nodes written to output.

Error goes away if you set "target" to "es6"
[-]compile error: "Too many nodes written to output"[/-][+]compiler exception: "Too many nodes written to output"[/+]dkent600 commentedon Dec 15, 2016
Error also goes away if you use regular javascript
forloops, like:This is a work-around
