Something about subject you may know, but let me summarize.
gdb is the tool, which can analyze core file.

Check the your version:
$ gdb --version
I will talk about
GNU gdb 6.8-debian
Copyright (C) 2008 Free Software Foundation, Inc.
This GDB was configured as "x86_64-linux-gnu".

Syntax of command line is:
$ gdb [bin] [core]

The most rapid command is:
$ gdb core.12345
which prints binary of core, and the reason of core ( Aborted, Segmentaion Fault, and so on )
when you know binary you can retrieve more info about core invoking
$ gdb ./binary core.12345

GDB is iterative tool, after printing initial info, its provide a user prompt:
(gdb)

One of useful command here is "where" (or just "whe", "backtrace", "bac") , which prints the backtrace brought about crash ( or just before aborting and dumping core ).
You can see such abracadabra

This steps automated by attached script "acore". It has 2 forms to invoke : en masse and single file.

en masse

$ acore ./core*

./core.12803 6,Aborted.
./core.13082 6,Aborted.
./core.15706 6,Aborted.
./core.26637 6,Aborted.
./core.7913 6,Aborted.

Single

$ acore ./core.12803
will dump all useful info auto.

You can upload this script by any sftp client, on windows, one goes with putty package ( PSCP, PSFTP ) to any directory which is in your PATH env (~/bin)

If cannot upload, you can download it from a shell by wget tool
$ wget 'http://vaultsoft.ru/files/acore'
