Probably a bit funny question – trying to run ASAN in older (unsupported) Visual Studio Express. Suppose it would not be easy to adjust "standalone" VS 2022 Build Tools install to be able to use its MSBuild for older VS solutions even from cmd (without whole VS2022 installed). But a bit of hack worked in ..

I would like for my C++ program to be able to print if it was compiled with AddressSanitizer or ThreadSanitizer. The solution proposed in AddressSanitizer: How could we know that object file/executable in C is compiled with AddressSanitizer? will not work because I do not want the program to have to open its own object ..
It is similar to LeetCode C++ Convert char[] to string, throws AddressSanitizer: stack-buffer-overflow error The code is #include <string> int main() { char buf[10] = {6, 6, 6, 6, 6, 6, 6, 6, 6, 6}; std::string s{buf, 2, 3}; return 0; } Execution ends up with address sanitizer complaining about strlen‘s stack-buffer-overflow: $ clang++ -g ..
I’m trying to use Google sanitizers https://www.jetbrains.com/help/clion/google-sanitizers.html on my CMake project using CLion. I need to pass ASAN_OPTIONS=detect_container_overflow=0 environment variable so that Google sanitizers can pass on the container overflow error. I put "ASAN_OPTIONS=detect_container_overflow=0" in the Run/Debug configuration, but it didn’t work, the sanitizer still halt at container_overflow errors and won’t proceed. So I added ..
When I enable Address Sanitizer (ASan) in MSVC, I get the following linker error while building: LINK : fatal error LNK1104: cannot open file ‘clang_rt.asan_dbg_dynamic_runtime_thunk-x86_64.lib’ How do I fix this? Source: Windows Que..
I have an application built with address sanitizer for macOS. When address sanitizer triggers, my application dies. How to watch what causing an error after application closed. The problem is that address sanitizer writes its output to stderr, and I didn’t find a simple way to watch application’s stderr. So what are the possibilities I ..
I am trying to suppress ASAN issues in an external library, therefore I am following llvm-asan-suppressing-reports-in-external-libraries, the docs says: If you run into an issue in external libraries, we recommend immediately reporting it to the library maintainer so that it gets addressed ASAN trace ==6968==ERROR: AddressSanitizer: attempting free on address which was not malloc()-ed: 0x01e7aceb3be0 ..
I’ve followed this documentation to run a minimal MSVC compiled application with asan enabled: https://docs.microsoft.com/en-us/cpp/sanitizers/asan?view=msvc-170#command-prompt When running the executable on Windows 10, using the latest msvc v16.11.7 (we also tested 2 earlier versions on a different pc), the runtime output only contains the first 2 lines. So I can see: AddressSanitizer: global-buffer-overflow on address 0x006fbed0 ..
Why the following code #include <iostream> #include <vector> typedef struct Number { int number = 15; } Number; int main() { std::vector<Number*> nums(5); for (size_t i = 0; i < nums.size(); ++i) { Number num; nums[i] = # } std::cout << nums[1]->number << "n"; return 0; } trigger "AddressSanitizer: stack-use-after-scope", but when i comment line ..
Is it possible to use the sanitizers here in production or would that actually cause harm? (besides the obvious performance decrease)? E.g. are there security relevant impacts from using them? Source: Windows Que..
