Out of stack space while compiling

[jovdb]

When I run this piece of nonsense code, the compiler crashes.
I know this code is completely invalid but maybe this can somehow stabilize the compiler.

TypeScript Version: 2.4.1 (No compiler flags used)

Code

class Animal {}

interface IAnimal extends Animal {
	foo(): IAnimal[];
	bar<TAnimal extends IAnimal>(): TAnimal;
}

interface IBird extends IAnimal {
	foo(): IPigeon[];
}

interface IPigeon extends IBird {
	bar(): IPigeon;
}

Expected behavior:
Compiler error(s), no stack overflow
Didn't test if in 'watch mode' this stops the watching.

Actual behavior:
Script failed with error: 'JsErrorScriptException (0x30001)'.
Out of stack space
Error: Out of stack space

Just got hit by this as well. FWIW, tsc v2.3.4 and v2.4.0 have no problem compiling the same project.

Run tsc in this directory: https://github.com/Vincit/objection.js/tree/master/examples/express-ts

@RyanCavanaugh is there anything else I can provide to help debug?

@mceachen I had a similar issue which went away after installing the v2.5 nightly (typescript@next) - maybe give that a try?

[mceachen]

2.5.0-dev.20170712 and 2.5.0-dev.20170707 behave the same as 2.4.1 for the abovementioned repository, but thanks for the suggestion, @clownwilleatme .

I've found a workaround: #17097 (comment)

This no longer repros with typescript@latest.
