One would expect it to core, then, when you ran out of memory; you said (in your original posting) that it was the FreeBSD version of the code that cored?!? > 2- is faster for this particular case of bad programing. Don't expect FreeBSD to ever optimize system code to make bad programmers look like good programmers.

If you are fighting that fight, you might as well switch to Windows, and be done with it, because people can make the same argument with "Windows vs. Linux" instead of "Linux vs. FreeBSD", since the issues are exactly analogous: the Windows environment does a much better job than Linux of allowing bad programmers to write code that runs. And Linux does this better than FreeBSD (there are even Linux libraries that will treat NULL pointers as if they were pointers to strings with a value of "" -- and don't think there isn't runtime overhead associated with the extra compares again NULL for each and every strcpy(), strlen(), etc.. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
