Confirmed. Shorter testcase (crashes with "-O -ftree-loop-distribution"):

=====================================
int foo();

void bar()
{
  int i, j, x[2], y[2], z[2];

  for (i = 0; i < 2; ++i)
    if (foo())
    {
      for (j = 0; j < 2; ++j)
        if (z[j])
          z[j] = 0;

      for (j = 0; j < 2; ++j)
      {
        x[j] = 0;
        y[j] = 0;
      }
    }

  if (x[0] && y[0])
    foo();
}
=====================================
