gcc memcpy "knows" about types that are supposed to be actually already aligned and triggers alignment errors doing the memcpy itself. "Fix" this by changing it to a bcopy(). In this case, we had: struct timeval *tp; struct timeval tv1; memcpy(&tv1,tp,sizeof(tv1)); .. and since gcc *knows* that a pointer to a timeval is longword aligned and that tv1 is longword aligned, then it can use an inline that assumes alignment. The following works too: cp = (char *)tp; memcpy(&tv1,cp,sizeof(tv1)); Simply casting (char *)tp for the memcpy doesn't work. :-( This affected different 64 bit platforms in different ways and depends a lot on gcc as well. I've seen this on alpha and ia64 at least, although alpha isn't doing it right now. |
