vmthread-sourcemap-repro

Reproduction case for vmthreads getting the wrong sourcemap location

Steps

• Install deps yarn install or npm install
• Run tests yarn test or npm test

With pool: 'threads', location works as expected

 FAIL  src/__tests__/sum.test.ts > sum
TypeError: Cannot set properties of undefined (setting 'name')
 ❯ Module.sum src/sum.ts:7:12
      5|
      6| export function sum(items: Item[]): number {
      7|   items[3].name = "break!";
       |            ^
      8|   return items.reduce((acc, item) => acc + item.count, 0);
      9| }
 ❯ src/__tests__/sum.test.ts:10:10

With pool: 'vmThreads', location is wrong:
