BUG: Using Referenced Integer to Access Array Generates CXX0034

ID: Q168430

The information in this article applies to:

The Integrated Debugger, used with:
- Microsoft Visual C++, 32-bit Editions, versions 4.0, 4.1, 4.2, 5.0, 6.0

SYMPTOMS

The Visual C++ debugger generates the following error while using a referenced integer to access array.

Error: CXX0034: types incompatible with operator

The MORE INFORMATION section below contains a sample showing this behavior.

RESOLUTION

The workaround is not to use referenced integer a[i] to access array as shown in the sample. Use index value instead, as a[1].

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Steps to Reproduce Behavior

Build the following sample with debug information:


   //test.cpp
   int func(int& i, int a[])
     {
      return 0;
     }

   int main(void)
     {
     int a[] = {1, 2, 3};
     int  i = 1;
     func(i, a);// SET A BREAKPOINT HERE
       return 0;
     }

Start the debugger with a breakpoint shown. If you now step into func() by hitting the F11 key and put a watch on "a[i]," you will get the error mentioned above. However, evaluating "i" and "a[1]" works just fine.
