I saw a compiler warning that looks like a typo and can cause a problem.
/home/smvv/work/jhbuild/checkout/webkitgtk-2.17.4/Source/WebCore/css/CSSFontStyleValue.h: In member function ‘bool WebCore::CSSFontStyleValue::isItalic() const’:
/home/smvv/work/jhbuild/checkout/webkitgtk-2.17.4/Source/WebCore/css/CSSFontStyleValue.h:53:49: warning: enum constant in boolean context [-Wint-in-bool-context]
return valueID == CSSValueItalic || CSSValueOblique;
A fix would be:
return valueID == CSSValueItalic || valueID == CSSValueOblique;
It looks like Myles picked this fix up in Bug 174149.
