[LLVMdev] instr_iterator

Is it safe or legal to call isInsideBundle even when I == E?

MachineBasicBlock::iterator MachineBasicBlock::getFirstNonPHI() {
  instr_iterator I = instr_begin(), E = instr_end();
  while (I != E && I->isPHI())
  assert(!I->isInsideBundle() && "First non-phi MI cannot be inside a
  return I;

I am seeing an assert when I run llc.
The code is in lib/CodeGen/MachineBasicBlock.cpp:145.
