I was now able to pinpoint the problem.  (You know that I don't give 
up...)  Consider the attached example problem and add the following 
compiler option:

 	-fvisibility=hidden

Then, it will crash in the way I described.  (I am using g++ version 
4.4.3.)

Can anybody tell me why this happens?

Best Regards,
