    Memory Management How do I deal with memory leaks? By writing code that doesn’t have any. Clearly, if your code has new operations, delete operations, and pointer arithmetic all over the place, you are going to mess up somewhere and get leaks, stray pointers, etc. This is true independently of how conscientious you are with your allocations: eventually the complexity of the code will

  • CppCon 2016: Leak-Freedom in C++... By Default--Herb

    May 15, 2017Lifetime safety means writing code that, by construction, is guaranteed to eliminate two things: (a) use of null/dangling pointers (including pointerlike things such as references, iterators, views, and ranges), and (b) leaks (including the rare 1% case where we’re tempted to admit the possibility of an ownership cycle or need to support lock

  • C++ Core Guidelines - GitHub Pages

    Similar examples can be constructed “leaking” a pointer from an inner scope to an outer one; such examples are handled equivalently to leaks of pointers out of a function. A slightly different variant of the problem is placing pointers in a container that outlives the objects pointed to.

  • Root Cause - Chris Rohlf

    IsoAlloc exposes API calls to assist in program development such as detecting memory leaks (iso_alloc_detect_leaks), and verifying the heap state (iso_verify_zones). These are useful in defensive programming designs where performance is not the first priority but they can also be used during fuzzing or test development.

  • What is Dangling Pointer with Cause and How to avoid it?

    Dangling pointers in computer programming are pointers that pointing to a memory location that has been deleted (or freed). Dangling pointers arise during object destruction, when an object that has an incoming reference is deleted or deallocated, without modifying the value of the pointer, so that the pointer still points to the memory location of the deallocated memory.

  • Comp.compilers: Re: Strong/weak pointers

    Weak pointers are a solution to this problem. For example, only parent-child is a strong pointer, rest are all weak pointers. Links formed using weak pointers do not form edges in the cycle. An important decision weve made is that every variable in the language IS a strong pointer. That is, there is no pointer* notation.

  • Smart pointers/safe memory management for C - Stack

    You cannot do smart pointers in C because it does not provide necessary syntax, but you can avoid leaks with practice. Write the resource release code immediately after you allocated it. So whenever you write a malloc, you should write the corresponding free immediately in a cleanup section. In C I see the GOTO cleanup pattern a lot:
