"Pretty much anything that speaks ANSI C" is my usual feeling about that. As yet we have not heard of any non-gcc compilers in which this is a problem, although you have a point that some compiler somewhere may do this and not have a way to turn it off :-( > Also note that uninhibited casting between types can still cause alignment > problems, We understand that issue, we solved it years ago. BTW, I haven't looked at the problem spots in detail. How many of them are due to the use of MemSet in conjunction with other access to a chunk of memory? ISTM that we need not worry about code motion around a MemSet call, since that would require the compiler to prove that the memset() path through the macro wouldn't be affected, which I doubt it would think. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
