Comment (by dwmw2):

 Picking the ones that are dead easy to find the error by hand... these all
 happen to the msb of a byte at 0xXXX27, getting flipped from 0 to 1:

 The one at 0xb7c8b1c should have a CRC of 0x6e105f72. I haven't checked
 the rest of the CRCs but the bogus length field (0x80000xxx) is obvious.
