segmentation fault

[Oliver Block <lists@block-online.eu>]

Hello,

a program causes a segmentation fault and I'd like to know if I interpret the 
following gdb output correctly (text continues after output):
************************************************************************************
#1  0x4012eb3f in gethostbyname () from /lib/tls/libc.so.6
No symbol table info available.
#2  0x08049312 in http_send_recv (hostname=0x804a340 "www.oliver-block.eu",
    request=0x804b030 "GET /checkip.php HTTP/1.0\r\nHost: 
www.oliver-block.eu\r\n\r\n") at ddnscli.c:168
        hptr = (struct hostent *) 0x804b068
        sptr = (struct servent *) 0x804b028
        sin = {sin_family = 2, sin_port = 0, sin_addr = {s_addr = 0},
  sin_zero = "\000\000\000\000\000\000\000"}
        s = 134514323
        retval = 45
        n = 0
        buflen = 1024

        tmp = 0x0
        r = 0x804b030 "GET /checkip.php HTTP/1.0\r\nHost:

        option = 8 '\b'
        q = (struct query *) 0x804b008
(gdb) p sizeof(struct servent)
$1 = 16
****************************************************************************
When I extract

from #2:
sptr = (struct servent *) 0x804b028

from #4:
r = 0x804b030 "GET /checkip.php HTTP/1.0\r\nHost: www.oliver-block.eu\r\n\r\n"

as servent has a size of 16 bytes

804b028 + 16 = 0x804b038

These two variables seem to overlap. Do you agree? 

Regards,

Oliver
