Crashes on transform and parse (from assertion/debug failures) about typescript HOT 4 OPEN

Could you try to narrow it down? It's almost impossible to fix this without knowing what source files lead to the problem.

from typescript.

I have filtered out the ts files that can cause the above problem and located the code lines in the files that may cause errors.
I have modified tsconfig.json，and used version 5.4.5 of the tsc testing program on the Ubuntu 22.04.3 LTS platform.

I have provided configuration files, TS source files, and specific error messages in this repository：https://github.com/Roise-yue/tscFuzz

from typescript.

Yes, one thing you could try is to keep deleting files until you've found a culprit. Then when you've narrowed things down to as few files as possible, try to delete as many lines of code as you can.

from typescript.

Thank you so much for finding these @Roise-yue! I'm copying those files into this comment to make it easier to follow - the transform crash is from the use of the accessor keyword used in certain spots:

// @target: esnext
// @noTypesAndSymbols: true

abstract class C1 {
    accessor accessor a: any;
    readonly accessor b: any;
    declare accessor c: any;
    accessor public d: any;
    accessor private e: any;
    accessor protected f: any;
    accessor abstract g: any;
    accessor static h: any;
    accessor i() {}
    accessor get j() { return false; }
    accessor set k(v: any) {}
    accessor constructor() {}
    accessor l?: any;
    accessor readonly m: any;
    accessor declare n: any;
}

class C2 extends C1 {
    accessor override g: any;
}

interface I1 {
    accessor a: number;
}

accessor class C3 {}
accessor interface I2 {}
accessor namespace N1 {}
accessor enum E1 {}   // Error location
accessor var V1: any;
accessor type T1 = never;
accessor function F1() {}
accessor import "x";
accessor import {} from "x";
accessor export { V1 };
accessor export default V1;
accessor import N2 = N1;

And the other error I haven't been able to verify independently, but I'm pasting it here.

// @importHelpers: true
// @target: es5
// @module: commonjs
// @moduleResolution: classic
// @experimentalDecorators: true
// @emitDecoratorMetadata: true
// @filename: external.ts
export * from "./other";
export class A { }
export class B extends A { }

declare var dec: any;

@dec
class C {
    method(@dec x: number) {    // Error location
    }
}

const o = { a: 1 };
const y = { ...o };
const { ...x } = y;

// @filename: other.ts
export const x = 1;

// @filename: script.ts
class A { }
class B extends A { }

declare var dec: any;

@dec
class C {
    method(@dec x: number) {
    }
}

// @filename: tslib.d.ts
export {}
