Re: Bug in _VFPRINTF_R


I'm sorry Eric, but I gave you a specific example :
   printf("%.*s\n",len,(char *)NULL) /* len = 0 */

and not printf("%s", (char *)NULL)

In my example, I think the result should be empty an not (null)

According to Samuel Vinson on 9/15/2007 1:35 AM:
I never see that with different libc implementation, I used
(linux/gcc/libc/glibc, windows/msvcrt, solaris/libc...)

It may not match msvcrt or solaris libc, but it does match glibc - I'm not sure how you tested it.

Perhaps POSIX and C99 allow your choice, but this is not portable in
different platforms.

This is not portable, period. Calling printf("%s", (char*)NULL) invokes undefined behavior, and is a bug in your program, not in newlib.
