How to programmatically cause a core dump in C/C++

Question

I would like to force a core dump at a specific location in my C++ application.

I know I can do it by doing something like:

int * crash = NULL;
*cras         


        

Answer 1

A few years ago, Google released the coredumper library.

Overview

The coredumper library can be compiled into applications to create core dumps of the running program -- without terminating. It supports both single- and multi-threaded core dumps, even if the kernel does not natively support multi-threaded core files.

Coredumper is distributed under the terms of the BSD License.

Example

This is by no means a complete example; it simply gives you a feel for what the coredumper API looks like.

#include 
...
WriteCoreDump('core.myprogram');
/* Keep going, we generated a core file,
 * but we didn't crash.
 */

It's not what you were asking for, but maybe it's even better :)
