extremely minimal compile with -fsanitize=address creates faulty executable

[Phildo]

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 (in a vcvars64.bat env):
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).

update: it looks like this error only occurs with a vcvars64.bat command prompt

update: I take it back. if I use the WinMain version, the bug does not repro in command prompt. but it does repro regardless when run from my editor (10x). note that it doesn't matter from where I compile it- only where I run it...

Presumably, this was fixed by 160e8eb

Does this mean the problem will persist until MS ships clang/LLVM 18 via the VS Installer, unless we install the toolchain by other means?

Now similar one happens with

-- Clang C++ compiler: C:/Program Files/LLVM/bin/clang++.exe
-- The CXX compiler identification is Clang 19.1.1 with GNU-like command-line

with using -m32:

==8652==interception_win: unhandled instruction at 0x02031110: 8b 4d 10 8b c1 53 56 57

Instruction "8B 4D XX : mov XX(%ebp), ecx" should be fixed by 57466db, included in branch release/20.x.
