>Description:
        The fnmatch(3) C library function is broken on OpenBSD 5.8. Negated
        character classes such as [![:space]] aren't matched.
        The following test program outputs "fnmatch broken" on OpenBSD and
        "fnmatch ok" on Mac OS X and Linux. (On NetBSD, it's broken too.)
>How-To-Repeat:
        #include <stdio.h>
        #include <fnmatch.h>
        int main() {
          int result=fnmatch("[![:space:]]", "x", 0);
          if (result==0) {
            printf("fnmatch ok\n");
            return(0);
          } else {
            printf("fnmatch broken\n");
            return(1);
          }
        }

        Not known to me.
