            Bug ID: 214341
           Summary: [GTK] accessibility/datalist.html is crashing in debug
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: lmoura at igalia.com

Sample crash log

r257833                       TEXT (Expected: FAIL) 
r257839                       CRASH (Expected: FAIL)

It does not fail on its own, it needs to be run twice or with some other test in front of it in the same WTR process (i.e. --run-singly does not crash).

Sample trace (line numbers from attached file from build 6742/r264371)
