This reduction gives a different (but probably related) ICE:

void crash_me(int num1, int num2, char * in, char * out)
{
  int i, j;
  for (j = 0; j < num1; j++)
    for (i = 0; i < num2; i++)
      *out++ = *in++;
}

$gcc -O1 -floop-interchange -c crash_me.c
crash_me.c: In function 'crash_me':
crash_me.c:7: error: unrecognizable insn:
(insn 24 22 25 6 test.c:5 (set (reg:DI 70)
        (reg:SI 62 [ D.1626 ])) -1 (nil))
crash_me.c:7: internal compiler error: in extract_insn, at recog.c:2038
