Function name is not displaying in GDB

Question

I have the core dump file. I kept the c binary application(Built with Debug ON option) in the GDB path which caused the core dump along with the core file.

But when I do GDB, I am getting the stack information as below:

sura@hyde:/abc/def/ghi/appln [css_absmin] gdb application_name core_1206
HP gdb 3.0 for PA-RISC 1.1 or 2.0 (narrow), HP-UX 11.00.

warning: exec file is newer than core file.
Core was generated by 'application_name'.
Program terminated with signal 11, Segmentation fault.

(gdb) where
#0  0xc0199640 in ?? ()
(gdb) bt
#0  0xc0199640 in ?? ()
(gdb) 

The C Binary is compiled in PA-RISC (unix).

How can I get the offending function name?

Sundar,

You posted a question about gdb but HP-UX gdb is not a GNU gdb, but rather gdb customized by HP. So it is called Hewlett-Packard Wildebeest (based on GDB) - wdb. Your problem is that you have extremely old version of wdb. Right now HP offers gdb 6.5 (http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4cbcdc3f3515b49c108973a801/?ciid=29080f1bace021100f1bace02110275d6e10RCRD) for HP 9000 systems running HP-UX 11i v1, 11i v2, or 11i v3 and your version is 3.0!

You seem to have HP-UX 11.00, so you can ask on HP-UX forum what is the latest wdb for HP 11.00. Ask here: http://h30499.www3.hp.com/t5/Languages-and-Scripting/bd-p/itrc-150#. Also after installing the latest wdb for your PA-RISC try to get backtrace again with it. I hope you will get a correct backtrace with the latest wdb.
