The crash comes from this call: https://github.com/qtwebkit/qtwebkit/blob/qtwebkit-5.212.0-alpha3/Source/W= ebCore/css/CSSParser.cpp#L6907 Can you commet comment this line, recompile qtwebkit and see what happens? Either this line: https://github.com/qtwebkit/qtwebkit/blob/qtwebkit-5.212.0-alpha3/Source/W= ebCore/css/CSSParser.cpp#L6897 does not work properly or this is broken: https://github.com/qtwebkit/qtwebkit/blob/qtwebkit-5.212.0-alpha3/Source/W= ebCore/css/CSSValuePool.cpp#L121-L134 I'd like to see to see the content of familyName when passed. Either via breakpoint or with std::cout. Unfortunately, my C++ knowledge is minimal. I recommend to write a minimal C++ app with a function call and signature "const String& str" and then pass the string [1]. Since this is a custom type, I don't know whether cout will work. You have to try. Michael [1] https://github.com/adobe/webkit/blob/master/Source/WTF/wtf/text/WTFString.= h
