This regression showed up starting with this patch:
--- gcc/ChangeLog ---
2002-08-02 Jason Merrill <jason@redhat.com>
* langhooks-def.h (LANG_HOOKS_EXPR_SIZE): New macro.
* langhooks.c (lhd_expr_size): Define default.
* langhooks.h (struct lang_hooks): Add expr_size.
* explow.c (expr_size): Call it.
* expr.c (store_expr): Don't copy an expression of size zero.
(expand_expr) [CONSTRUCTOR]: Use expr_size to calculate how much
to store.
* Makefile.in (builtins.o): Depend on langhooks.h.
--- gcc/cp/ChangeLog ---
* cp-lang.c (LANG_HOOKS_EXPR_SIZE): Define.
(cp_expr_size): New fn.
* call.c (build_over_call): Lose empty class hackery.
(convert_arg_to_ellipsis): Promote non-POD warning to error.
* typeck.c (build_modify_expr): Don't use save_expr on an
lvalue.
The ICE can be reproduced on i686-linux with the reduced
test case.

>Description:
This is similar to pr8748 (and many more ICEs in cp_expr_size in the past) but it's not yet fixed in the branch (pr8748 is btw.)
The testcase is short, so it's inline (extracted from some KDE code):
------------ snip -----------
struct QString
{
QString( const QString & );
QString &operator=( const QString & );
};
struct ServerSettings
{
QString user;
};
extern ServerSettings def();
extern void arg( const QString& a );
void startSession( bool b, QString s )
{
arg (b ? def().user : s);
}
---------- snap -----------
>How-To-Repeat:
> $PATH_3_3/bin/g++ -O -c above.ii
above.ii: In function `void startSession(bool, QString)':
above.ii:14: internal compiler error: in cp_expr_size, at cp/cp-lang.c:304
