Infinite loop while viewing cache stats page

           Summary: Infinite loop while viewing cache stats page
           Product: Apache httpd-2.0
           Version: 2.0-HEAD
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_ldap
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: minfrin@sharp.fm


The following code in util_ldap_cache_mgr.c gets stuck in an infinite loop:

    for (i=0; i < cache->size; ++i) {
        if (cache->nodes[i] != NULL) {
            nchains++;
>>          for (n = cache->nodes[i]; n != NULL; n = n->next)
	        totchainlen++;
        }
    }

In the above case, the variables n, cache->nodes[i] and n->next all point to the
same object, so "n = n->next" causes an infinite loop.
