c++cclangaddress-sanitizer

An extremely simple program triggers an 'unhandled instruction' error when compiled with sanitizers

I have this trivial C code (it could be C++)

$ cat .\main.c
#include <stdio.h>

int main() {
    printf("Hello");
    return 0;
}

When I compile it with address sanitizer.

clang -fsanitize=address main.c

And run, I get this error.

.\a.exe
==11224==interception_win: unhandled instruction at 0x7ff7d86bffd3: 4c 8d 15 26 00 f5 ff 49
AddressSanitizer: CHECK failed: sanitizer_common_interceptors_memintrinsics.inc:239 "((__interception::real_memcpy)) != (0)" (0x0, 0x0) (tid=8888)
    <empty stack>

Without address sanitizer, the program prints the message.

Environment:

Windows 11 & LLVM installed throughout choco

$ clang --version
clang version 17.0.5
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\LLVM\bin

I am doing something wrong? This should work fine, right?

Solution

  • I can confirm that we reproduce this problem.

    Location of files: %ProgramFiles%\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC

    Problem is in VS package: 14.38.33130 or maybe in newer or small older. Microsoft done a lot of changes in 14.38.33130 and we receive the same problem <empty stack>.

    Temporary solution:

    1. Go to %ProgramFiles%\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\
    2. delete the package "14.38.33130" or other
    3. copy there package "14.36.32532"
    4. Rename directory name from "14.36.32532" to "14.38.33130"(or other which you had before)

    In my opinion external LLVM and CMake is not compatible with new Visual Studio package.

    Please note Microsoft change it just 1-3 weeks ago so a lot of person have older package and can not reproduce the problem, until upgrade the module.
