it seems warn(0) and err(1,0) segfault
(they should handle fmt==0 before passing
it to vfprintf)
and they do not print the ': ' nor the
__progname
(perror works correctly)
test program:
#include <stdio.h>
#include <err.h>
int main()
{
warn("warntest");
warn(0);
perror("perrortest");
perror("");
perror(0);
}
$ gcc err.c && ./a.out
a.out: warntest: Success
a.out: Success
perrortest: Success
Success
Success
$ musl-gcc err.c && ./a.out
warntestNo error information
Segmentation fault (core dumped)
