 This problem still exists in 3.3 20021008 and 3.2.1 20021009 on
 i686-pc-linux-gnu.  As mentioned earlier, it's a regression from
 GCC 2.95.3.
 
 The PR name ought to be "c++" rather than "middle-end".
 
 At the time of the ICE in find_function_data, 'exp' in expand_expr is
 a SAVE_EXPR whose function context, 'context', is cloned from
 'current_function_decl'.  The code in expand_expr falsely assumes that
 since 'context' is different from 'current_function_decl', 'context' is
 a containing function.  It calls find_function_data just to make sure
 that 'context' is for a containing function, but it's not so that
 function aborts.
 
 I don't where to go from here, but hope that this information will be
 of use to someone familiar with the C++ front end.
