For this to work, you'll need not only the 'core', but also a system
with the *exact* same shared libraries (patches and all), or you
would not be able to interpret the 'core'.

Some details here:

In practice, you'll be quite unlikely to be able to interpret the
'core' correctly on any system other then the one it was produced on.

What I do is ask the customer to run whatever debugger commands I
would have performed. The output, coupled with non-stripped
executable, is sufficient to understand where the crash happened.

Use 'gcc -g -O2 ...' as Chuck Dillon suggested.
