Bug 203036 – REGRESSION(r251124): [GTK] Crashes in service workers tests

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Carlos Alberto Lopez Perez]

Since r251124 several service worker related tests crash on platform GTK.

Here are different crash logs from the debug bot obtained on r251177:

https://build.webkit.org/results/GTK%20Linux%2064-bit%20Debug%20(Tests)/r251177%20(5409)/results.html

All related to service workers crash on the same part.


This is the relevant part of the crash, piped to c++filt:

extended crash log for test http/tests/workers/service/image-fetch.html with a debug build on r251187

I'm attaching a more detailed crash log with the values of variables.
Has been obtained on a debug build on r251187 when running the layout test http/tests/workers/service/image-fetch.html
