Looks like it has been fixed. Anything non-zero means strcmp says the
strings are not equal, so not just -1:

Right, sorry: the return value should be a[0]-b[0], which is (1 - 0) = 1, not -1. Anyways, yeah, bug fixed. :)

 

(unstable-sparc64-sbuild)root@andi:/tmp# gcc -O0 test.c -o test64
(unstable-sparc64-sbuild)root@andi:/tmp# ./test64
1
(unstable-sparc64-sbuild)root@andi:/tmp# cat test.c
/* test.c */
#include <stdio.h>
#include <string.h>

int main() {
  char a[2] = { 1, 0 };
  char b[2] = { 0, 0 };
  printf("%d\n", strcmp(a,b));
}
(unstable-sparc64-sbuild)root@andi:/tmp#

This has been tested with gcc_5.2.1-23 and glibc_2.19-22 on sparc64.

Cheers,
Adrian
