Bug ID: 250569
Summary: Terminated worker memory leak
Product: WebKit
Version: Safari Technology Preview
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: jaffathecake at gmail.com
Not sure this is the correct component. This bug is something to do with workers/js/wasm.
1. Go to https://safari-worker-memory-leak-demo.netlify.app
2. Click "draw using threads", and wait for the result. Repeat this step around 20 times.
I start getting "rangeerror: Out of memory".
Each run of "draw using threads" spins up a worker, which in turn starts other workers. The root worker is terminated once the operation is complete.
I wonder if the inner workers are not being correctly collected when the parent worker terminates.
