 According to gdb this should be here:
 
    0x17becc <bswap64>:  movel %sp@(4),%d1
    0x17bed0 <bswap64+4>:        movel %sp@(8),%d0
    0x17bed4 <bswap64+8>:        rolw #8,%d1
    0x17bed6 <bswap64+10>:       rolw #8,%d0
    0x17bed8 <bswap64+12>:       swap %d1
    0x17beda <bswap64+14>:       swap %d0
    0x17bedc <bswap64+16>:       rolw #8,%d0
    0x17bede <bswap64+18>:       rolw #8,%d1
    0x17bee0 <bswap64+20>:       rts
    0x17bee2:    nop
 
 and
 
 0x17bed4 <bswap64+8>:   0xe159e158
 
 Could this be something later overwritten? Bad RAM?
