C++ Programs Terminate with Abnormal Error

This error typically occurs when customers write a "Hello World" type C++ application like this: 

#include <CHM/CHMengineClass.h>

int main()
{
   CHMengine Engine;
   Engine.Load("../vmd/sorter.vmd");
}

When the program runs, it produces an unfriendly error message: 

Assertion:
 CHMengineCreate(&Handle) in file CHMengineClass.cpp at line 26
 Hint: put a breakpoint at line 292 in the file CHMerrorClass.cpp to 
       easily locate the exception location.
Abort(coredump)

An exception is being thrown (as shown above). It's really important to put the try/catch block around the code to catch the exception. For example: 

#include <CHM/CHMengineClass.h>
#include <CHM/CHMerrorClass.h>
#include <iostream.h>

int main()
{
   try
   {
      // Ensure that the engine is inside the try/catch block
      // to gracefully handle exceptions thrown from the constructor.
      CHMengine Engine;
      Engine.Load("../vmd/sorter.vmd");
   }
   catch (CHMerror& Error)
   {
      cerr << Error;
   }
}

When a try/catch block is correctly position around the code, your application will output a more friendly error message that accurately explains the problem. The most common errors occur when mandatory environment variables are not set in Unix. For more information, please see the following sections:
