The threaded program used in this ticket crashes intermittently.  The error is 
sometimes "terminate called after throwing" and something "unwind called 
recursively".  A sample stack trace is shown below.

Previous frame identical to this frame (corrupt stack?)


To reproduce the bug, copy this program to "main.cpp" and compile it with "g++ -
pthread main.cpp".  Then, run the program with "while ./a.out do sleep 1; 
done".  After a minute or so, the program will die.  (It doesn't die every 
time, so that is why you need to run it in the loop.)
