This really unrelated to that fortran bug. Anyways I might take a look soon.

------- Comment #3 from pinskia at gcc dot gnu dot org 2006-05-31 07:53 -------
Confirmed, reduced testcase:
struct gc{};
struct transform:public gc
{
double x, y, z, t;
transform (void){}
};
inline transform f (void)
{
return transform ();
};
void transformed (void)
{
new transform (f());
}
------------------------------------------------
This is return slot related and inline related, we have:
*D.2030 = f () [return slot optimization];
........
__comp_ctor (&<retval>);
return <retval>;

------- Comment #5 from janis at gcc dot gnu dot org 2006-06-07 18:23 -------
A regression hunt on powerpc-linux with the testcase in comment #3 identified
this mainline patch:
http://gcc.gnu.org/viewcvs?view=rev&rev=112709
r112709 | rguenth | 2006-04-05 15:41:18 +0000 (Wed, 05 Apr 2006)
The same patch was added to the 4.1 branch a couple of days later, so I assume
it's also the cause of the failure there. GCC 4.1.0 does not fail.

I guess the patch uncovered a latent problem due to different inlining. I will
have a look though.
