In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...
Whether a precise collector is practical usually depends on the type safety properties of the programming language in question. An example for which a conservative garbage collector would be needed is the C language, which allows typed (non-void) pointers to be type cast into untyped (void) pointers, and vice versa.
Other languages, such as C and C++, were designed for use with manual memory management, but have garbage-collected implementations available. Some languages, like Ada, Modula-3, and C++/CLI, allow both garbage collection and manual memory management to co-exist in the same application by using separate heaps for collected and manually managed ...
In computer science, manual memory management refers to the usage of manual instructions by the programmer to identify and deallocate unused objects, or garbage.Up until the mid-1990s, the majority of programming languages used in industry supported manual memory management, though garbage collection has existed since 1959, when it was introduced with Lisp.
In GCC on Linux, this can be done using the following commands for a C program: $ gcc yourProgram.c -g $ ./a.out Memory leak information will be reported in the file specified by the MALLOC_TRACE environment variable.
I would like to see more about the history behind when these were implemented in different computing systems. I see a strong parallel to telephone switching, but can't find any sources. See this video about the No 5 Crossbar on YouTube (XKyXCZV_faY) at 9:31 about what is basically a stack trace for a mechanical computer.
The language, inspired by C, includes added functions and variables specific to tracing. D programs resemble AWK programs in structure; they consist of a list of one or more probes (instrumentation points), and each probe is associated with an action.
Another approach to preventing stack buffer overflow exploitation is to enforce a memory policy on the stack memory region that disallows execution from the stack (W^X, "Write XOR Execute"). This means that in order to execute shellcode from the stack an attacker must either find a way to disable the execution protection from memory, or find a ...
