gdb: lose of stack frames or function name missing

[Alex Cicco]

Hi, there:

Thank you in advance for your help.  

I am using gdb to debug my C++ program, which contains a lot of
template classes.

This is how I compiled and linked:
g++ -c -ggdb myProg.cc
g++ -o myProg myProg.o

When I run myProg, I got a core dump and I intended to use gdb to
debug.

I used two Unix systems.

System 1: gdb version 5.0, g++ version 3.0.2.  
   In this system, after loading the core using "gdb myProg core", I
issued gdb command "where".

   The following is what I get
   (gdb) where
   #0  0xef65c840 in _libc_kill () from /usr/lib/libc.so.1
   #1  0xef5f5ab4 in abort () from /usr/lib/libc.so.1
   #2  0x13da0 in Letext ()

   It appeared that function where core dumped is not in the frame
stack.  The frames listed here are just from linked libraries.

Q1:  Is there any way to include the functions from main to which the
core is dumped in the stack frame?

System 2: gdb version 4.17, g++ version 2.95.3.  
   In this system, after loading the core using "gdb myProg core", I
issued gdb command "where".
   The following is what I get
   (gdb) where
   #0  0xef65c840 in ?? ()
   #1  0x13da0 in ?? ()
   #2  0x157b0 in ?? ()
   #3  0x14284 in ?? ()
   #4  0x14644 in ?? ()
   #5  0x13a2c in ?? ()
   
   It appeared that functions where core dumped upto the main are
included in the frame stack.  However all the function names are
garbled.
   I set the following variables in gdb
      set demangle-style gnu
      set print asm-demangle on
      set print demangle on

   Function names are still garbled.

Q2:  Is there any way to have the function name being listed?  

I am a novice on gdb. I do not have .gdbinit, may be one would solve
all the problems above?

Q3:  Where can I get a "standard" .gdbinit?

To be honest, I am enthusiastic in using gdb and I have spent quite a
lot of time in reading tutorials.  I hope I can use it doing my
debugging routine.  However, I tried a dbx debugging session and the
complete fram stack can be printed out with function names (below).

I am convinced that I must have done something wrong in using gdb. 
Please give me your kind advise.

Thank you very much.

Alex

PS:
The frame stack from dbx debugging session looks like:

(/opt/SUNWspro/bin/../WS6U2/bin/sparcv9/dbx) where
  [1] _kill(0x0, 0x6, 0x0, 0xffffffff, 0xff2bc414, 0xff2356d8), at
