I'm actually seeing this with pygccxml svn version:

/usr/local/lib/python2.5/site-packages/pygccxml/parser/scanner.py:335:
UserWarning: unable to find out array size from expression ""

It is triggered by something as simple as:

class Something{
[...]
    static void Parse (int argc, char *argv[]);
};

The relevant source code  is:

    def __read_array_type( self, attrs ):
        type_ = attrs[ XML_AN_TYPE ]
        size = self.__guess_int_value( attrs.get(XML_AN_MAX, '' ) )
        if size is None:
            size = array_t.SIZE_UNKNOWN
            msg = 'unable to find out array size from expression "%s"' %
attrs[ XML_AN_MAX ]
            warnings.warn( msg )
        return array_t( type_, size + 1 )

In this case attrs is:
 {'max': '', 'align': '64', 'type': '_1769', 'id': '_2010', 'min': '0'}

I don't know how to fix, but I hope this helps.

Cheers, and Happy New Year! :-)
