This stacktrace suggest that you've built your application with
single-threading, and linked it to multi-threaded build of 
program_options, or vice versa.

I don't think I can suggest more without the real code and specific
information how you build it.

My code is broken down into 2 projects - one compiles into a static
library and the other into an executable that is referring to the static
library.
I am using several boost libraries - multithreaded versions.  When I
compile and link I use -pthread compiler flag. 

By the way, I did an experiment where I commented out everything in my
main method and only left a call to the trouble-maker class.  Everything
works fine then.  In the same file I also have a helper function that
uses shared_ptr library.  When I uncomment that function, but don't
envoke it, I still get the same problem.

Is there anything else I should be doing to get this to work correctly?
