使用 MSYS2 中的 LLVM-C api 返回退出代码 1，但使用 WSL 工作正常

Question

i installed llvm+clang using MSYS2, and all the tools work fine for me, but the LLVM-C always returns exit code 1, here is my sample code:

#include <llvm-c/Core.h>
#include <stdlib.h>

int main(int argc, char const *argv[]) {
    LLVMModuleRef mod = LLVMModuleCreateWithName("my_module");

    LLVMPrintModuleToFile(mod, "my_module.ll", NULL);

    LLVMDisposeModule(mod);
    return 0;
}

it compiles on MSYS2, but it returns exit code 1, and does not write the module to the file,

but when compiled using WSL, it returns exit code 0 and writes to the file.

i am using these MSYS2 packages:
https://packages.msys2.org/package/mingw-w64-x86_64-clang?repo=mingw64
https://packages.msys2.org/package/mingw-w64-x86_64-llvm?repo=mingw64

i did not try the C++ LLVM api, but i am assuming that does not work as well.

here are the commands i run:
powershell:

$x = llvm-config --cflags --ldflags core --system-libs --libs
clang $x hello.c -fuse-ld=lld
./a.exe
echo $lastExitCode # returns 1

bash:

clang `llvm-config --cflags --ldflags core --system-libs --libs` hello.c
./a.out
cat my_module.ll

nvm 我修复了它，我的解决方案是我没有使用 powershell，而是使用了 MSYS2 (MinGW-w64) shell。
