Analyzing Core Dump
We have a binary that generates coredump. So I ran the gdb command to analyze the issue. Pleae note the binary and code are in two different locations and we cannot build the whole binary using debugging symbols. Hence how and what details can I find from below backtarce:

Code:
gdb binary corefile

(gdb) where
#0  0x101fa37a in f1()
#1  0x10203812 in operator f2< ()
#2  0x085f6244 in f3 ()
#3  0x085f1574 in f4()
#4  0x0805b27b in sigsegv_handler ()
#5  <signal handler called>
#6  0x1018d945 in f5()
#7  0x1018e021 in f6()
..................................
#29 0x08055c5c in main ()
(gdb)

Please provide me gdb commands that I can issue to find what’s data inside each stack frame , what’s the issue probably is, where it is failing, other debugging methods if any?

Thanks in advance

dh_builddeb

DH_BUILDDEB(1)							     Debhelper							    DH_BUILDDEB(1)

NAME

       dh_builddeb - build Debian binary packages

SYNOPSIS

       dh_builddeb [debhelperoptions] [--destdir=directory] [--filename=name] [--params]

DESCRIPTION

       dh_builddeb simply calls dpkg-deb(1) to build a Debian package or packages.  It will also build dbgsym packages when dh_strip(1) and
       dh_gencontrol(1) have prepared them.

       It supports building multiple binary packages in parallel, when enabled by DEB_BUILD_OPTIONS.

       When the Rules-Requires-Root field is not (effectively) binary-targets, dh_builddeb will pass --root-owner-group to dpkg-deb(1).

OPTIONS

       --destdir=directory
	   Use this if you want the generated .deb files to be put in a directory other than the default of "..".

       --filename=name
	   Use this if you want to force the generated .deb file to have a particular file name. Does not work well if more than one .deb is
	   generated!

       -- params
	   Pass params to dpkg-deb(1) when it is used to build the package.

       -uparams
	   This is another way to pass params to dpkg-deb(1).  It is deprecated; use -- instead.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
