------- Comment #1 from pinskia at gcc dot gnu dot org 2006-05-02 07:22 -------
Confirmed, not fixed by the patch which fixes PR 26626.
Here is a reduced Fortran testcase:
MODULE parallel_rng_types
INTEGER, PARAMETER :: dp=KIND(0.0D0)
TYPE rng_stream_type
REAL(KIND=dp), DIMENSION(1) :: bg,cg
LOGICAL :: antithetic
END TYPE
CONTAINS
SUBROUTINE reset_to_next_rng_substream(rng_stream,error)
TYPE(rng_stream_type), POINTER :: rng_stream
LOGICAL :: failure
CALL cp_assert(ASSOCIATED(rng_stream),routineP,error,failure)
IF (.NOT.failure) THEN
rng_stream%bg = u
rng_stream%cg = u
END IF
END SUBROUTINE reset_to_next_rng_substream
END MODULE
-----
I might get a reduced C one soon or not.

And here is the C example (so this does not become not release blocking):
typedef struct atype
{
float bg[1], cg[1];
_Bool ant;
}atype;
void cp_assert(_Bool*, float*, int*, _Bool*);
void f(atype **rng_stream, int *error, float u)
{
_Bool t = *rng_stream != 0;
float routinep;
_Bool failure;
cp_assert ( &t, &routinep, error, &failure);
if (failure == 0)
{
typedef float ty[1];
ty *tt = &((*rng_stream)->bg);
int i = 1;
do
{
(*tt)[i - 1] = u;
i ++;
}while (i > 1);
{
ty *tt = &(*rng_stream)->cg;
int i = 1;
do
{
(*tt)[i - 1] = u;
i ++;
}while (i > 1);
}
}
}

This is a different bug, in fact.
Those two (D.1547_18 and D.1547_12) should have had the exact same SMT
base, AFAICT, and thus, should have had the same result.
What do the alias dumps look like after the patch from 26626?

------- Comment #6 from fxcoudert at gcc dot gnu dot org 2006-05-14 09:00 -------
Any progress on this one? It's blocking a few widely-used Fortran codes from
compiling (and being used and benchmarked) with mainline gfortran.

We aren't marking smt usage for updating in forwprop, but we need to, because
forwprop is propagating and address and destroying the smt info.
