How do I enable sanitizers with MSVC?

To enable sanitizers with Microsoft Visual C++ (MSVC), you can use the following instructions.

Microsoft provides tools to help detect memory-related programming errors through the use of Address Sanitizer and other analysis tools in Visual Studio. To use it, ensure you're using Visual Studio 2019 (version 16.7 or later) or a newer version.

Here’s how to enable Address Sanitizer in a project:

# Include the sanitizer header #include // Example function with a memory issue for demonstration void testFunction() { int* array = new int[10]; // Access out of bounds to trigger Address Sanitizer int outOfBounds = array[10]; delete[] array; } int main() { testFunction(); return 0; }

To compile the program with sanitizers enabled, use the following command in the Developer Command Prompt for Visual Studio:

cl /fsanitize=address yourfile.cpp

After doing this, when you run your compiled program, Address Sanitizer will provide you with detailed reports on memory access errors and leaks.
