The largest possible memory block malloc can allocate depends on the host system, particularly the size of physical memory and the operating system implementation. Theoretically, the largest number should be the maximum value that can be held in a size_t type, which is an implementation-dependent unsigned integer representing the size of an ...

Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.
In C code, segmentation faults most often occur because of errors in pointer use, particularly in C dynamic memory allocation. Dereferencing a null pointer, which results in undefined behavior, will usually cause a segmentation fault. This is because a null pointer cannot be a valid memory address.
Placement new can also be used as a simple debugging tool, to enable programs to print the filename and line number of the source code where a memory allocation has failed. This does not require the inclusion of the Standard C++ library header <new> , but does require the inclusion of a header that declares four placement functions and a macro ...
Memory corruption errors can be broadly classified into four categories: Using uninitialized memory: Contents of uninitialized memory are treated as garbage values. Using such values can lead to unpredictable program behavior. Using non-owned memory: It is common to use pointers to access and modify memory.
A memory debugger is a debugger for finding software memory problems such as memory leaks and buffer overflows. These are due to bugs related to the allocation and deallocation of dynamic memory . Programs written in languages that have garbage collection , such as managed code , might also need memory debuggers, e.g. for memory leaks due to ...
Intel Inspector (previously known as Intel Thread Checker) is a memory and thread checking and debugging tool to increase the reliability, security, and accuracy of C/C++ and Fortran applications. Reliability: Find deadlocks and memory errors that cause lockups & crashes; Security: Find memory and threading vulnerabilities used by hackers
