"The CWriter::GetValueName() method does not check if a value as an alias 
and emits the alias name which will never be defined in the output .c 
file (so the output file fails to compile). This can happen if you have 
multiple inheritance with several destructors defined by clang (...D0Ev, 
...D1Ev, ...D2Ev)."

-- applied with minor tweaks. Thanks!
