That would be 0.95+cvs20040624-126.96.36.199.pure64 or
0.95+cvs20040624-188.8.131.52.pure64 then. Earlierversions didn't have the
lines below. :)
Please check which one since the later should only print the lines on
error and the numbers don't match an error condition.

Lets compare that to the code:
| if ((addr < RAW_ADDR (0x1000))
0x555cd200 < 0x55556000 => false
| || (addr < RAW_ADDR (0x100000)
0x555cd200 < 0x55655000 => true
| && RAW_ADDR (mbi.mem_lower * 1024) < (addr + len))
0x555f5000 < 0x555cd201 => false
| || (addr >= RAW_ADDR (0x100000)
0x555cd200 >= 0x55655000 => false
| && RAW_ADDR (mbi.mem_upper * 1024) < ((addr - 0x100000) + len)))
0x555f5000 < 0x554cd201 => false

This confuses me even more.
Are you sure there is no 'D: ERR_WONT_FIT <number>' printed?
