Ok, I've rewritten the test program and it works now for me:
$ LD_LIBRARY_PATH=/usr/glibc/glibc-2.1/lib /usr/glibc/glibc-2.1/lib/ld-linux.so.2 ./crash 
there
here -1

Paul, I really think that's ok now.  What do you think?

/* no need to even call strcmp -- ld.so will do that for you */
int strcmp(char *a, char *b)
{

    printf("there\n");
    while(*a && *b) {
	if (*a < *b) {
	    return -1;
	} else if (*a > *b) {
	    return 1;
	}
	a++; b++;
    }
    if (*a == '\0' && *b == '\0')
    	return 0;
    
    return *a < *b;
}

int
main()
{
    printf("here %d\n", strcmp ("a", "b"));
    return 0;
}
