🙂 Expected behavior

$ npx tsc
(List of type errors.)

Additional information about the issue

NOTE:
It's not a node(24.4.1) issue, I tried with a different node version (node:22-bookworm from dockerhub).
The project is tiny.
I tried adding all my free rams to node (12GB) it ate it.

Steps to reproduce:

# Download this branch: https://github.com/fxdave/cuple/pull/new/typescript-issue-5-8-memory-leak
git clone -b typescript-issue-5-8-memory-leak https://github.com/fxdave/cuple.git
cd cuple

# Setup:
npm i
make build # Important!

# run npx tsc in the tests folder
cd test
npx tsc

(the code contains errors, but that shouldn't matter.)

Tái hiện với branch typescript-issue-5-8-memory-leak của repository cuple: chạy npm i, chạy make build, sau đó cd test và chạy npx tsc. So sánh TypeScript 5.8+ với 5.7 bằng project được cung cấp và xác nhận rằng quá trình biên dịch báo lỗi kiểu thay vì làm cạn kiệt heap.
