What are common address sanitizer errors and how can I fix them?

Common address sanitizer errors include heap buffer overflow, stack buffer overflow, and use-after-free. These errors occur when your program accesses memory that it shouldn't. To fix them, you can use tools like Valgrind or review your code for proper memory management.

Can you explain what a heap buffer overflow is?

A heap buffer overflow occurs when a program writes more data to a block of memory allocated on the heap than it can hold. This can corrupt data, crash the program, or create security vulnerabilities.

How can I prevent these errors in my code?

To prevent these errors, always ensure that you allocate enough memory for your data, use safe functions that limit the amount of data written, and regularly test your code with tools like AddressSanitizer.

What tools can help me detect these errors?

You can use tools like AddressSanitizer, Valgrind, and GDB to detect and debug memory-related errors in your code.
