SYMPTOMS
If a constant expression that evaluates to zero is used to allocate an array, the following error occurs:
RESOLUTION
To work around the problem, use a variable that is initialized to zero in place of the constant when allocating the array.
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++, 32-bit Edition, version 2.0.
MORE INFORMATION
The operator new() can be called with the argument zero. A distinct (non- null) pointer to an object will be returned (see Section 5.3.3 of the ARM - M.A.Ellis, B.Stroustrup). This is the behavior observed with Visual C++ version 2.0.
The following sample code can be used to demonstrate the problem.
Sample Code to Reproduce Problem
/* Compile options needed: none */ char * p = new char[0]; // Causes C2466
