What makes you think so? The only relevant difference between 2.30 and 2.84 is that structs are now individually marked as packed too, but that should be a nop because the whole section is bracketed by #pragma pack anyway. The problem is that the seq_nr and ack_nr fields in PacketFormat (in utp.cpp) are misaligned. I don't quite know under what circumstances gcc should handle direct loads/stores of these fields, but in practice where pointers to different structs are cast back and forth and eventually dereferenced, this blows up. > Any Transmission users able to test especially on say sparc64?
