This line in freetds.conf:
        dump file append = yes
when used with  "dump file = ...", causes a segmentation fault on startup
of freetds-0.61.  Here is a (partial) stack backtrace (from sqsh):

#1  0x400fa90a in fprintf (stream=0x0, 
    format=0x400349e0 "Starting log file with debug level %d.\n")
    at fprintf.c:32
#2  0x400247c6 in tdsdump_open (filename=0x807cc20 "/tmp/freetds.log")
    at util.c:201
#3  0x40024f48 in tds_connect (tds=0x807bfe8, connect_info=0x807c2d0)
    at login.c:222

Note the NULL (0x0) stream pointer tdsdump_open() is passing to fprintf().
When tds_g_append_mode is 1, the log file has not yet been opened when FreeTDS
tries to write this first message "Starting log file...".
("dump file append" worked at FreeTDS-0.60, before this message was added.)
