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

Yet another failure with -ftree-vectorize on mainline
(compile with "-ftree-vectorize -msse2 -O" on i686-pc-linux-gnu):

======================================
double x[3];

void foo()
{ 
    int i;

    for (i=0; i<3; ++i) x[i]=0;
    for (i=0; i<2; ++i) ;
}
======================================

bug.c: In function 'foo':
bug.c:4: internal compiler error: in var_ann, at tree-flow-inline.h:115
Please submit a full bug report, [etc.]
