Model:   F40
OS:      AIX 4.3
>Description:
Invoking the C++ front-end, specifying XCOFF object output, on a source file containing a simple base class and subclass declaration:

   $(GCC_HOME)/lib/$(PLATFORM)/$(VERSION)/cc1plus -gxcoff How-To-Repeat.ii

generates the following message:

   <stdin>:7: internal compiler error: in tree_low_cst, at tree.c:3228

The referenced tree.c is in $GCCSRC/gcc, NOT $GCCSRC/gcc/cp.

The ICE disappears if the -gxcoff switch is removed.
>How-To-Repeat:
// filename: How-To-Repeat.ii
// a simple base class and subclass declaration
//
// compile with -gxcoff (assuming the compiler has
// support for it) to reproduce the problem

class BaseClass
{
   int x;
};

class Subclass : public BaseClass
{
  int y;
};
>Fix:
Choose one:
- don't declare subclasses
- don't use the -gxcoff switch
