Internal compiler error for K6

[Martin Erhardsen]

The current snapshot (20000508) won't compile this small program for K6
with -O2.

int n,a[10]; char b[10];
void foo (void)
{
  int j;
  for (j = n-1; j >= 0; j--)
    if (a[j] && b[j]) return;
}

[root@foo gcc]# stage1/xgcc -Bstage1/ -c -march=k6 -O2 test1.c
test1.c: In function `foo':
test1.c:7: Internal compiler error in `verify_wide_reg_1', at flow.c:2588
