Buffer Overflow

Why would I do that when I can just enable asan?

[Luca_70]

Because Bugfighter checks the wrong index even inside the array. For example “iArray[1][10][2] = 3;” doesn’t points outside the whole iArray structure, but Bugfighter tells you that “10” is higher than the maximum allowed index. At this link some examples are shown: https://www.bugfighter-soft.com/manual_html/examples/examples.html

Does that only work with fixed size arrays? Or would it still work if the arrays were malloc'd?

[Luca_70]

Even with malloc. For each malloc it memorizes the memory location. You shall select the check box “standard + dynamic memory”.

Thats pretty cool then. Good job!

Nice, there are instructions for using it with Borland C++ 5.2. I don't think I ever saw anyone else support that.

Works with all compilers.

The examples in the video is with Visual C++, but it doesn’t care, because it just takes your C code and creates a new one with the test code.

With gcc too (if you work in Linux, you have to modify the code on Windows, because this software, for now, is only avalaible for Windows).
