Can not debug cyrus imapd code

[neelu_dhiman at persistent.co.in]

Hi,
I am working on Cyrus Imap server (Fedora Core). I have to
modify the Cyrus code, for which I found out the places and
started debugging the imapd code. But, I am recieving
segmentation Fault and different signals in between. If I
login to server directly through a client, then it works fine.
But debugging the code is having problems. 

(gdb)
cmd_fetch (tag=0x9b05f00 "5", sequence=0xd40acdf9 <Address
0xd40acdf9 out of bounds>, usinguid=0) at imapd.c:2592
2592        struct strlist *newfields = 0;
(gdb)

Program received signal SIGSEGV, Segmentation fault.
0x080549a6 in cmd_fetch (tag=0x9b05f00 "5", sequence=0x2710
<Address 0x2710 out of bounds>, usinguid=0) at imapd.c:2590
2590        int fetchitems = 0;
(gdb)
Couldn't get registers: No such process.
(gdb) q

Please guide.
Thanks
Neelu.
