 This is exactly the same error as c++/9524.
 
 
 Ciao,

 No.  I tested multiple compilers.  clean HEAD, clean 3.3, and clean
 hammer-3_3-branch (Ok, the last with one patch to the backend, but it
 can't matter).

 I would hope so too, yes.
 
 
 Ciao,

 Valid question. I am building straight from CVS, on a SuSE 8 box. Are you 
 using additional SuSE patches?
 
 At any rate, 9868 seems to be a superset of the problem in 9524, so should 
 9868 be fixed, this would likely cure 9524 as well, and for both of us.

 Ahh, yes. I forgot.  It would be interesting to know in which way our
 compilers differ, that even the frontend behaves differently.  Hmm.

 Correct, at least close. I had a problem with 9524 before, and still have: 
 it doesn't ICE on mainline for me. It does, however, if I make the class 
 in 9524 a template, as above. So I think they are not exactly the same.
 
 I'd like to keep both open, for this reason, but will post a note to 9524 
 to link it to 9868.
 
 Thanks for pointing out the connection
   W.

Old Synopsis: ICE building LyX 1.3.0 with Qt frontend on HP-UX 11i with GCC 3.3 prerelease
New Synopsis: [3.3/3.4 regression] ICE in c_expand_expr when qualifying member variable

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Thu Feb 27 15:30:24 2003
State-Changed-Why:
    This is an extract:
    ---------------------------
    template <typename T> struct D {
        void (*p)();
    
        void clear() { D::p(); }
    };
    template class D<bool>;
    --------------------------
    D::p was previously in a base class, which is why it is
    qualified with Class::. The code above crashes 3.3 and 3.4:
    g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
    x.cc: In member function `void D<T>::clear() [with T = bool]':
    x.cc:6:   instantiated from here
    x.cc:4: internal compiler error: in c_expand_expr, at c-common.c:4339
    
    It worked with 3.2.2, though, so it's a regression.
