["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following testcase causes an ICE on i686-pc-linux-gnu when compiled with
"-O -march=pentium4 -ftree-vectorize":

===============================
double d[3];

void foo() 
{ 
    int i;
    for (i=0; i<3; ++i)
        d[i] = 0;
}
===============================

bug.c: In function 'foo':
bug.c:4: internal compiler error: in get_bb_copy, at cfg.c:1078
Please submit a full bug report, [etc.]

The regression was introduced yesterday (2005-06-15).
