Summary: Crash in
WebCore::AXObjectCache::performDeferredCacheUpdate
Product: WebKit
Version: Other
Hardware: PC
OS: Linux
Status: NEW
Severity: Normal
Priority: P2

Unfortunately this backtrace is horrible and probably not going to be useful at all for fixing the bug, but we have a crash somewhere in
WebCore::AXObjectCache::performDeferredCacheUpdate detected on the GTK release bot when running layout test imported/w3c/web-platform-tests/html/syntax/parsing/html5lib_tests9.html. I'm not going to add a crash expectation because the test has only ever crashed once:
