Old Synopsis: Internal error in g++ on compiling Qt-retated code (PerlQt module)

State-Changed-Why:
    Confirmed.
    
    The code is in fact illegal, since in x_QTSManip::x_0 we have the expression
    
           (QTSMFI)x[1].s_int
    
    with x[1].s_int being an int and QTSMFI being defined as
    
           typedef int (QTextStream::*QTSMFI)(int);
    
    Mainline correctly reports
    
    x_QTSManip.cpp: In static member function `static void 
       x_QTSManip::x_0(Smoke::StackItem*)':
    x_QTSManip.cpp:10: error: invalid conversion from 'int' to 'int 
       (QTextStream::*)(int)'
    
    However, gcc 2.95.x - 3.2.1 fail with an ICE.
    A reduced testcase is the following:
    
    -----------------------snip here--------------------------
    struct A
    {
        typedef int (A::* P)(int);
        A(P);
    };
    
    A a((A::P)1);
    -----------------------snip here--------------------------
