GCC 4.5.2 (snapshot) and 4.4.5 (snapshot) don't exhibit this behavior and
compile the file fine.

I can provide preprocessed source for this if needed.

This issue looks more likely QT issues than a GCC one.  The attached file is
not unzipping for me though.

same here.
i experienced very similar bug/feature when compiled Psi jabber client as well.
looks like automatic calling proper constructor of object does not work well
anymore. or maybe some deprecated forms were removed from gcc.

Hmm, it seems that type "Enum' isn't automatical converted to 'int' anymore.
Does it help to add to template class QFlags the following constructor 'inline
QFlags(int f) : i((Enum)f) {}' ?

Mine.  This is a problem with my overload resolution hack from the implicitly
deleted patch.
