Bug 64551 – REGRESSION (r91003): 4 svg/dynamic-updates tests failing assertions in WebCore::createSharedCursor on Windows XP Debug (Tests)

• Component: Platform
• Status: NEW

[Adam Roben (:aroben)]

The following tests started failing assertions in WebCore::createSharedCursor on Windows XP Debug (Tests) in r91003 <http://trac.webkit.org/changeset/91003>:

    svg/dynamic-updates/SVGCursorElement-dom-x-attr.html
    svg/dynamic-updates/SVGCursorElement-dom-y-attr.html
    svg/dynamic-updates/SVGCursorElement-svgdom-x-prop.html
    svg/dynamic-updates/SVGCursorElement-svgdom-y-prop.html

http://build.webkit.org/results/Windows%20XP%20Debug%20(Tests)/r91002%20(30670)/results.html passed
http://build.webkit.org/results/Windows%20XP%20Debug%20(Tests)/r91003%20(30671)/results.html failed

Here's the asserting code:

FAULTING_SOURCE_CODE:  
    52:     HDC dc = GetDC(0);
    53:     HDC workingDC = CreateCompatibleDC(dc);
    54:     if (doAlpha) {
    55:         OwnPtr<HBITMAP> hCursor = adoptPtr(CreateDIBSection(dc, (BITMAPINFO *)&cursorImage, DIB_RGB_COLORS, 0, 0, 0));
>   56:         ASSERT(hCursor);
    57: 
    58:         img->getHBITMAP(hCursor.get()); 
    59:         HBITMAP hOldBitmap = (HBITMAP)SelectObject(workingDC, hCursor.get());
    60:         SetBkMode(workingDC, TRANSPARENT);
    61:         SelectObject(workingDC, hOldBitmap);

Does this still occur in recent Windows bots (since we've retired XP)?
