I am currently trying to debug a very elusive problem.  When running our code under Momentics, about every 10th run I 
will get the following error on the console:

pure virtual method called
terminate called without an active exception

and then my programs exits as if it terminated normally.  The debugger also terminates normally.  My program is multi-
threaded.  Since no exception or signal is being generated, the debugger doesn't break.  This happens regardless if the 
program is compiled for Debug or Release.  I need to set a breakpoint where this message is being generated, but this is
 happening in the bowels of the run-time libraries.  How do I debug this problem?

I am using QNX 6.5.0 and Momentics 4.7.0
