FIX: C1001 Error in 'msc1.cpp' on Template Function Parameter (152041)

SYMPTOMS

The following error is generated for template function with a parameter of scoped template member type:

   fatal error C1001: INTERNAL COMPILER ERROR
    (compiler file 'msc1.cpp', line 899)
    Please choose the Technical Support command on the Visual C++
    Help menu, or open the Technical Support help file for more information
   Error executing cl.exe.

Under Visual C++ 4.1, the error will occur at line 1090 instead of line 899. Under Visual C++ 4.2, the error will occur at line 1089. The sample code in the More Information section of this article demonstrates the presence of this error.

CAUSE

The reason for this error is the second parameter, Container::typA, in the template function funcA in the sample code. The compiler is unable to distinguish the scoped template parameter.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.
