>Description:
This is similar to pr8748 (and many more ICEs in cp_expr_size in the past) but it's not yet fixed in the branch (pr8748 is btw.)
The testcase is short, so it's inline (extracted from some KDE code):
------------ snip -----------
struct QString
{
    QString( const QString & );
    QString &operator=( const QString & );
};
struct ServerSettings
{
    QString user;
};
extern ServerSettings def();
extern void arg( const QString& a );
void startSession( bool b, QString s )
{
    arg (b ? def().user : s);
}
---------- snap -----------
>How-To-Repeat:
> $PATH_3_3/bin/g++ -O -c above.ii
above.ii: In function `void startSession(bool, QString)':
above.ii:14: internal compiler error: in cp_expr_size, at cp/cp-lang.c:304
