Bug 206868 – Regression: 30+ layout-test crash on Windows

• Status: RESOLVED
• Resolution: FIXED
• Component: Accessibility

[Aakash Jain]

30+ layout-test are crashing on Windows. This is a recent regression.

e.g.:
Build: https://build.webkit.org/builders/Apple%20Win%2010%20Release%20%28Tests%29/builds/4754
Results: https://build.webkit.org/results/Apple%20Win%2010%20Release%20(Tests)/r255170%20(4754)/results.html


Dashboard: https://results.webkit.org/?suite=layout-tests&test=accessibility%2Fnon-data-table-cell-title-ui-element.html

It indicates regression range between r255161-r255170.

    Frame[02]  Ignore Symbol: [WebKit!WebView::WebViewWndProc+0x5a8]

There was only one accessibility change in that range, https://trac.webkit.org/r255167
