Bug 182604 – [GTK] imported/w3c/web-platform-tests/WebCryptoAPI/derive_bits_keys/pbkdf2.worker.html is flaky

• Status: NEW
• Component: WebKitGTK

[Miguel Gomez]

Varies between pass and crash.

Please do post the backtrace for the crash from the bots. Crash reports are not very useful without a backtrace.

It started failing when you added the crash expectation, because that overrode the toplevel expectations. You didn't do anything wrong there IMO, it was just bad luck; I think it's a waste of time to check the toplevel expectations for every change. I've changed our expectation to [ Pass Failure Slow Crash ].

There is never any backtrace:

It's not the only test this happens to. Something is wrong with the bots. (Perhaps it is missing network process crashes, or UI process crashes?)
