Stack overflow occurs when your program uses up the entire stack. The most common way this happens is when your program has a recursive function which calls itself forever. Every new call to the recursive function takes more stack until eventually your program uses up the entire stack.

On Windows a stack overflow exception will be generated. The following windows code illustrates this: CONTEXT context; // we are interested control registers. context.ContextFlags = CONTEXT_CONTROL; // get the details. GetThreadContext(GetCurrentThread(), &context); // print the stack pointer. printf("Esp: %X\n", context.Esp);

Oct 2, 2024 · Running the application under the debugger in Visual Studio will show a StackOverflowException in the exception helper dialog and highlight the line of code responsible for making the final call that overflows the stack. The …

Here is an example of how to debug a stack overflow. In this example, NTSD is running on the same computer as the target application and is redirecting its output to KD on the host computer. See Controlling the User-Mode Debugger from the Kernel Debugger for details.

Jul 12, 2016 · GCC provides a few compiler flags to help diagnose and identify stack problems. A great first step and heading off stack overflows is to use -fstack-usage. This compiler flags generates worst case scenario stack usage on a per function basis. This information is generated at compile time and placed in .su files in the project directory.

Aug 1, 2019 · In this article, let’s discuss how stack overflow occurs, best practices to prevent it and how to detect if it actually occurred. Let’s start with what is stack and how it is implemented on microcontrollers.

Handling a stack overflow is not the right solution, instead, you must ensure that your program does not overflow the stack. Do not allocate large variables on the stack (where what is "large" depends on the program). Ensure that any recursive algorithm terminates after a …

Dec 23, 2022 · One of the first steps in detecting potential stack overflow problems is to check the program’s memory usage. This can be done by running the program in a memory profiler or by checking the output of the program in a debugger.

Sep 7, 2016 · The basic idea is to fill the stacks with a known bit fashion, aka, painting the stack, and then have code that monitors how much of that stack is being consumed by determining how much of the stack no longer contains the known bit pattern.

Feb 19, 2023 · How to avoid stack overflows in embedded applications? There are several ways, and a simple one is writing a defined pattern on the stack and then monitor how much of that has been overwritten. This article explains how to do this on ARM Cortex-M.

You can check the value of the variable in the main loop to see after-the-fact that the stack has overflowed. Or if your debugger allows, set a breakpoint when that variable is written. It should be written only when it is initialized.

This article provides some tips on how to use CCS to check for a stack overflow.

Jan 7, 2020 · You might be able to tell if that's a stack address by printing the addresses of a few stack variables to see where the stack is in the address space. You could determine how to tell the compilation system to allocate more space to the stack.

Sep 28, 2019 · In this article I describe an approach with the GNU gcc in a bare-metal (no RTOS) environment, because FreeRTOS already includes an option to check for a stack overflow at runtime: the check is performed at task context switch, see “FreeRTOS – stacks and stack overflow” for more details.

Feb 5, 2016 · If you get such a signal and determine that it comes from a stack overflow, raise the soft stack limit with setrlimit and set a global variable to identify that this occured. Make the variable volatile so the optimizer doesn't foil your plains.

To activate stack checking, compile all units with the gcc switch -fstack-check. For example: Units compiled with this option will generate extra instructions to check that any use of the stack (for procedure calls or for declaring local variables in declare blocks) does …

Apr 30, 2018 · Many toolchains have an option to initialize the stack with a specific pattern. This will allow you to determine a 'high watermark' during runtime, and an indication of a stack overflow after a crash. Still, stack size is defined statically, and your responsibility. This means, you need to increase the size until it fits your application.

Jan 18, 2024 · In development environments, compilers and debuggers can offer warnings and tools to diagnose stack overflows. For example, a compiler might give a warning about functions that have no return,...

Stack overflow occurs when the stack size exceeds its predefined limit. This can happen due to several reasons, including recursive function calls, excessive memory allocation, or an infinite loop. Let's consider an example to understand this better.

Apr 13, 2015 · If you are cross-compiling with a recent GCC you might want to use -Wstack-usage=some length and/or -fstack-usage to check that every call frame is not too big, or to compute manually the required stack depth.
