I am on CentOS 6.4 32 bit and am trying to cause a buffer overflow in a program. Within GDB it works. Here is the output: [root@localhost bufferoverflow]# gdb stack GNU gdb (GDB) Red Hat Enterpris...

According to Wikipedia Computer scientists consider a language "type-safe" if it does not allow operations or conversions that violate the rules of the type system. Since Python runtime checks...

I was porting some older high-speed C++ code to C#, and the existing code made use of a pointer-based double-indirection pattern like this (written here in a C# syntax), using the stack as efficien...

According the documentation for std::Vec, calling shrink_to_fit() will cause the Vec's capacity to "drop down as close as possible to the length but the allocator may still inform the vector t...

With Deno being the new Node.js rival and all, the memory-safe nature of Rust has been mentioned in a lot of news articles, one particular piece stated Rust and Go are good for their memory-safe na...

Experimenting with the programming language Rust, I found that the compiler is able to track a move of a field of some struct on the stack very accurately (it knows exactly what field has moved). H...

If I have a struct that encapsulates two members, and updates one based on the other, that's fine as long as I do it this way: struct A { value: i64 } impl A { pub fn new() -> Self { A { va...

I understand the usage and superficial differences between weak and unowned in Swift: The simplest examples I've seen is that if there is a Dog and a Bone, the Bone may have a weak reference to th...

I've been trying to get my head around the Rust borrowing and ownership model. Suppose we have the following code: fn main() { let a = String::from("short"); { let b = String::from("a long lon...

Is it possible to either create a coding standard or use of a library that can be proved to eliminate any memory management errors in C++? I'm thinking of something like Java, it is just impossibl...

Safety critical projects do not recommend any dynamic allocations or freeing allocated memory. Only during elaboration/initialization phase of the program execution, it is allowed. I know most of...

Is it possible to manually clear out the contents of an object from memory? In particular, I'm dealing with NSData. I've tried using data.length = 0 and data.setData(NSData). I know ARC will com...

I have read somewhere that in a language that features pointers, it is not possible for the compiler to decide fully at compile time whether all pointers are used correctly and/or are valid (refer ...

I'd like to use Haskell's quickcheck library test some C code. The easiest way seems to be doing a foreign import and write a property on top of the resulting haskell function. The problem with thi...
