FIX: C1001 from Conditional Operator in Initializer

• The C/C++ Compiler (CL.EXE) included with: - Microsoft Visual C++, 32-bit Editions, version 5.0

SYMPTOMS

Use of the conditional operator in the member initialization list may cause the following error:

   test.cpp(20) : fatal error C1001: INTERNAL COMPILER ERROR
   (compiler file 'E:\utc\src\\P2\main.c', line 379)
   Please choose the Technical Support command on the Visual C++
   Help menu, or open the Technical Support help file for more information

RESOLUTION

Initialize the members in the function code instead of in the initialization list.

-or-

Modify the order in which the variables are declared. For example, with the following sample the error only occurs if you attempt to initialize the second variable rather than the first variable.
