Bug in glibc-2.1 for Sparc

[Juan Cespedes <cespedes@debian.org>]

	Hi.  I've discovered a nasty bug in glibc 2.1: arguments to
strcmp() (and possibly other functions) are evaluated more than once:

$ cat kk.c
#include <stdio.h>
#include <string.h>

static char * kk(void)
{
	printf("Got here!\n");
	return "yeah";
}

main()
{
	strcmp(kk(), "yeah");
}
$ gcc -O2 -o kk kk.c
$ ./kk
Got here!
Got here!
Got here!
$ _
