puts() receiving a NULL pointer is a bug. The standards don't specify what happens in this case (the behavior is "undefined"), and Solaris chose to do the safest thing; dump a core so that someone can track down the problem. > I mean, couldn't puts() check for its arg and do something "smart" if > it is NULL ? Well, it *could*, but that would (very slightly) slow down a common routine, and wouldn't help if someone passed (say) (char *)1 or some other invalid pointer. It's much more sensible just to crash.
