Comparing this the first significant difference I see (for telnet logs) 
is that "good" version does allocate a 180b buffer for the second 
flashing, and the "bad" one doesn't. They both allocate it for the first 
flashing.

This is present for "good" and absent for "bad":

> Debug: 885 27701 target.c:1523 target_alloc_working_area_try(): allocated new working area of 180 bytes at address 0x10000000
> Debug: 886 27701 target.c:1386 print_wa_layout():  * 0x10000000-0x100000b3 (180 bytes)
> Debug: 887 27701 target.c:1386 print_wa_layout():    0x100000b4-0x10007fff (32588 bytes)

A little lower for "good" version:

> Debug: 1039 28208 target.c:1386 print_wa_layout():  * 0x10000000-0x100000b3 (180 bytes)
> Debug: 1040 28208 target.c:1386 print_wa_layout():  * 0x100000b4-0x100010b3 (4096 bytes)
> Debug: 1041 28208 target.c:1386 print_wa_layout():    0x100010b4-0x10007fff (28492 bytes)

For the "bad" version:

> Debug: 1042 37309 target.c:1386 print_wa_layout():  * 0x10000000-0x10000fff (4096 bytes)
> Debug: 1043 37309 target.c:1386 print_wa_layout():    0x10001000-0x10007fff (28672 bytes)

Next differences are clearing lockups after double fault and HardFaults 
vs. "normal" restoring of operation after flashing.

4\/3!!
