| 46 Notice that when instruction INSN5 is reached, the while-stepping |
| 47 actions of both TP1 and TP3 are still being collected, and that TP2 |
| 48 had been collected meanwhile. The whole range of ff0001-ff0005 |
| 49 should be single-stepped, due to at least TP1's while-stepping |
| 50 action covering the whole range. |
| 51 |
