As it turned out, sizeof produces different results on 64-bit and 32-bit hosts because the size of the structure may aligned on whatever biggest alignment the gcc decides appropriate. It's not necesserily the biggest type, as on RISCs and Itanium, where accessing arrays of structs with misaligned sizeof will cause SIGBUS. As a result, our structs varied in size despite using fixed-size types. Our preferred fix is to pad structures so that they become more portable. This patch creates a flag day on 32-bit systems (but not on 64-bit ones). CLD clients and the daemon must be rebuilt. Signed-Off-By: Pete Zaitcev<zaitcev@xxxxxxxxxx>
