a page containing @font-face rule

Opening the attached page (containing @font-face rule) in latest Safari will crash Windows every time. My OS is Windows XP.
I also tried with WebKit ToT builds, the result is same. But the page works well with Chrome for Windows.
A simple investigation reveals it may relate to GDI font API. The following is the call stack before Windows crashes.

	DWORD GetGlyphOutline(HDC, UINT, UINT, LPGLYPHMETRICS, DWORD cbBuffer, LPVOID, const MAT2 *);
	WebCore::SimpleFontData::initGDIFont()
 	WebCore::SimpleFontData::platformInit()
 	WebCore::SimpleFontData::SimpleFontData(const WebCore::FontPlatformData &, bool, bool, WebCore::SVGFontData *)
 	WebCore::CSSFontFaceSource::getFontData(const WebCore::FontDescription &, bool, bool, WebCore::CSSFontSelector *)
 	WebCore::CSSFontFace::getFontData(const WebCore::FontDescription &, bool, bool)
 	WebCore::CSSSegmentedFontFace::getFontData(const WebCore::FontDescription &)
 	WebCore::CSSFontSelector::getFontData(const WebCore::FontDescription &, const WebCore::AtomicString &)
 	WebCore::FontCache::getFontData(const WebCore::Font &, int &, WebCore::FontSelector *)
 	WebCore::FontFallbackList::fontDataAt(const WebCore::Font *, unsigned int)
 	WebCore::FontFallbackList::primaryFontData(const WebCore::Font *)
