Another way might be to use the Google Coredumper library. This creates a similar result to the fork+abort technique but plays nicer with multithreaded apps (suspends all threads for a little while before forking so that they don't make a mess in the child).

Example:

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