Core dump

Hi ,
I want to read core dump file on AIX5.3. While i am trying to use following commands, i am getting only few lines of information.

Type 'help' for help.

Segmentation fault in malloc_common.extend_brk [/usr/lib/libc.a] at 0xd03719c4 ($t1)
0xd03719c4 (extend_brk+0x20c) 90040004 stw r0,0x4(r4)
(dbx) where
malloc_common.extend_brk(internal error: assertion failed at line 3650 in file frame.c
??, internal error: assertion failed at line 3650 in file frame.c
??, internal error: assertion failed at line 3650 in file frame.c
??) at 0xd03719c4
(dbx)
