Please report this issue at: https://github.com/rolldown/rolldown/issues/new?template=panic_report.yml
fatal runtime error: failed to initiate panic, error 5, aborting
Aborted (core dumped)Reproduction
On the rolldown-panic branch of this repo https://github.com/zengm-games/zengm/tree/rolldown-panic run this command:
$ node tools/watch/watchJs.ts
When it prints "Press ctrl+c now to see panic" (which happens after it calls watch) if I press ctrl+c I get a panic 100% of the time.
If you wait a bit longer it says "Too late!" - this is when the initial build from watch has completed, and then if you press ctrl+c there is no panic.
I made this as minimal as I could, but I couldn't fully isolate it because the panic goes away if I change many of these little details in watchJs.ts and watchJsWorker.ts such as:
- deleting the unused
node:fs/promises import
- deleting the empty
external function in the rolldown config
- deleting the
sportFunctions rolldown plugin, which runs a custom babel plugin on some files
- deleting the
exitHandler function
- making it run in the main thread rather than using node:worker_threads
