Hi, 
 
I get the mentioned ICE if I compile the following code with -g 
(gcc < 4 works fine): 
 
struct A 
{ 
    virtual int foo(); 
 
    double d; 
}; 
 
 
struct B : public A 
{ 
    A::d; 
}; 
 
 
int main() 
{ 
    return 0; 
} 
 
 
Cheers, 
André

Yes, but the link is wrong because the archives are messed up.

It seems rth's review got lost in the archives :(, so I'll cut'n'paste
from my mailbox:

I don't think this is the right approach.

Presumably we're suppressing debug for this class because it is "unused"?
If so, I can't think except that's a bug.  In this test case, A is used
twice -- once through the using and once through the inheritence.

Basically, I think it's wrong to try to emit just one field of a class.
If we need a field for some reason, then we need the entire class to put
it in proper context.

Jason replied to this that the compiler is already doing something similar,
see http://gcc.gnu.org/ml/gcc-patches/2005-02/msg00170.html
Daniel was wondering if gdb can handle it and I have tested that gdb
indeed handles this: http://gcc.gnu.org/ml/gcc-patches/2005-02/msg01230.html

Well, if we're already doing this, and the debugger handles it, then far be
it from me to stand in the way of progress.  Patch is ok everywhere.
