[reichelt at gcc dot gnu dot org]

------- Additional Comments From reichelt at gcc dot gnu dot org  2005-06-13 13:05 -------
Confirmed.

Shorter testcase (-O -ftree-vectorize -fdump-tree-copyprop3-details):

==============================
void foo(int* p)
{
    int i;

    for ( i=0; i<8; ++i )
        *p = 0;
}
==============================

bug.c: In function 'foo':
bug.c:2: internal compiler error: in op_iter_init_maydef, at
tree-flow-inline.h:1065
Please submit a full bug report, [etc.]

Since the bug also affects -fdump-tree-all-details this is a regression
from GCC 4.0.0.
