<pre>
    windows 11
clang 17.0.3 (installed via VisualStudio Community 2022)

main.cpp:
```
 int main(int argc, char** argv)
 {}
 ```
 or
 ```
#include <windows.h>
int APIENTRY WinMain(HINSTANCE hInst, HINSTANCE hInstPrev, PSTR cmdline, int cmdshow)
{ }
```

compiled with:
`clang -fsanitize=address main.cpp`
or
`clang++ -fsanitize=address main.cpp`

running the resulting executable outputs:
```
==22088==interception_win: unhandled instruction at 0x7ff649f1efb3: 4c 8d 15 46 10 f5 ff 49
AddressSanitizer: CHECK failed: sanitizer_common_interceptors_memintrinsics.inc:239 "((__interception::real_memcpy)) != (0)" (0x0, 0x0) (tid=3232)
 <empty stack>
```

(I also get the same error when using `-fsanitize=address` on my significant c++ project, but this is the literal minimal repro lol).
