1909322 - Visting about:config in GeckoView or Fenix causes a MOZ_ASSERT_UNREACHABLE in Development for APZHandledResult

Status: RESOLVED DUPLICATE of bug 1852854

(GeckoView :: General, defect)

Description

[Olivia Hall [:olivia]]

about:config is causing a crash for me in development in both Fenix and GeckoView Example. I could not reproduce in Nightly 130.0a1-20240720213208. So, likely this has been resolved. My current branch is here on July 18 commits.

I'll rebase to see if the issue is resolved, but filing now to prevent bug loss and while I still have the stack trace.

07-22 15:58:49.991 12812 12812 F MOZ_Assert: [12812] Assertion failure: false (MOZ_ASSERT_UNREACHABLE: nsEventStatus_eConsumeNoDefault should involve a valid APZHandledResult), at /Users/olivia/Repos/gecko/widget/android/nsWindow.cpp:971

(I don't have fix stacks setup right now, so the rest of the trace is libxul.so items.)

STR:

• Visit about:config
• Scroll

My mozconfig:

ac_add_options --enable-debug
ac_add_options --enable-project=mobile/android
ac_add_options --target=aarch64
ac_add_options --enable-crashreporter

My current branch is here on July 22 commits and it still crashes in development.

Best guess is the ac_add_options --enable-debug in development flag? The MOZ_ASSERT_UNREACHABLE is here.
