  • Closed as program error.

Error description

  • An infinite loop is seen in the C++ front end xlCentry component
    of the compiler when a const qualified template type is used:
    
    
        === TEST CASE ===
    
    class Test {};
    
    template <class T>
    struct MyStruct {
        typedef void (T::*CallType)()const;
    };
    
    int main() {
    
        //MyStruct<Test>::CallType t;        // Works
        MyStruct<const Test>::CallType t;    // Infinite loop
        return 0;
    }
    

Local fix

  • Remove const qualifier.
    

Problem summary

  • PROBLEM DESCRIPTION:
    Infinite loop caused by typedef const template definition.
    
    USERS AFFECTED:
    Users with typedef'd templates which have CV qualifiers.
    

Problem conclusion

  • An index variable that was not being updated was corrected, and
    users can now use CV qualifiers on typedef'd templates.
    

Temporary fix
