Coredump contains stack information as well. If you can use this stack information along with the EBP and EIP register values in the coredump file, you can print the stack trace. I had written a program to do this. You can find the program in the following link.

https://gist.github.com/root42/c979b037f85dc4b2be1f3735afedeb1d

Usage: Compile the above program and give the corefile when you execute it.

   $corestrace core

If you want symbols also to be printed, you do like this: Let's assume the program that generated the core is 'test'.
