title: How do I debug a core dump that aborted in a dlopen()'ed plugin?
body: <p>I have a core dump from a user. The main program loads selected plugins via <code>dlopen</code>. The process aborted in the plugin module. The user provided a backtrace that includes the filename of the plugin, and the function it aborted in.</p>
  
  <p>I need to look at data, such as arguments passed to the function. How do I tell gdb where the plugin was loaded, so it can figure out how to show the source and data?</p>
