Just for the record, I am aware of this bug, I have managed to
reproduce it on the sparc64 in the compile farm and have had a look at
it a few times already (albeit so far only briefly).
A few mechanisms within SRA come into play as we generate the integer
load statement which is wrong:
pkt_dst$s_addr_8 = MEM[(struct ip *)ip_3 + 7B].s_addr;
I will continue to try to figure out what to do about this but it is
not very straightforward.
