The octet order is screwy. words are LSB first (LS octet, actually), but
|
53 |
|
|
longwords are MSW first. For example, 0x12345678 is encoded 0x5678 in the
|
54 |
|
|
first word and 0x1234 in the second. When looking at the data as stored in

55 |
|

the COFF file, you would see the octets ordered as 0x78, 0x56, 0x34, 0x12.
