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 <[EMAIL PROTECTED]>
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.
