Or, at least that was the theory.  What is wrong with this picture:

1491                    rv = (*comp) (rec, elts[i].key, elts[i].val);
(gdb) p elts[i].key
$9 = 0x65568 "Vary"
(gdb) s
merge_vary_fields (d=0xac200, key=0x65568 "Vary", 
    val=0xaef0a "negotiate, accept-language, accept-encoding")
    at http_protocol.c:1469
1469        ap_table_merge(r->notes, "Vary-list", val);
(gdb) p val
$10 = 0xaef0a "negotiate, accept-language, accept-encoding"
(gdb) n
1471    }

Which is to say, strcasecmp("TCN", "Vary") is segfaulting.  Huh?
