I just tried to compile package lilypond-2.6.5-2 from Suse Linux with a recent
GNU C++ compiler version 4.2 snapshot 20060204.
The compiler snapshot said
rm -f ./out/drum-note-performer.dep;

------- Comment #4 from pinskia at gcc dot gnu dot org 2006-02-07 00:35 -------
Reduced testcase:
struct Pitch
{
int notename_;
};
struct Audio_note
{
Audio_note (Pitch p);
};
void create_audio_elements ()
{
Pitch *pit;
new Audio_note (*pit);
}
--------
Looks like this is caused by:
2006-01-30 Richard Guenther <rguenther@suse.de>
PR c++/23372
* gimplify.c (gimplify_target_expr): Handle easy cases
without creating a temporary.
------
The reason I said this patch is because the IR looks like:
(void) (TARGET_EXPR <D.2018, *(struct Pitch &) (struct Pitch *)
NON_LVALUE_EXPR <pit>>;, TARGET_EXPR <D.1993, (struct Audio_note *) operator
new (1)>;, try
{
__comp_ctor (NON_LVALUE_EXPR <D.1993>, D.2018);
}
catch
{
operator delete ((void *) D.1993);
}, D.1993) >>>
>>;
So we reduce the TARGET_EXPR to *pit but we reference D.2018 in the other
expression.

Ho humm, so I propose to revert the patch (that I didn't like very much
anyway). Can I do so without approval?

Yes but what about fixing the C++ front-end so that it does not place the
TARGET_EXPR in the wrong spot?
