Heap corruption on macOS x64 in `getaddrinfo()` when using object file

This only happens on macOS x64 when linking via object file. If using an archive file, it works fine.

The specific object file being linked is `CMakeFiles/mimalloc-obj.dir/src/static.c.o`. This works on linux amd64, linux arm64, and macOS arm64.

CMake command:
```bash
cmake -DCMAKE_C_COMPILER=/usr/local/opt/llvm@12/bin/clang-12 -DCMAKE_CXX_COMPILER=/usr/local/opt/llvm@12/bin/clang++ -DCMAKE_OSX_DEPLOYMENT_TARGET=10.14 -DCMAKE_BUILD_TYPE=Release -DMI_BUILD_SHARED=OFF -DMI_BUILD_STATIC=OFF -DMI_BUILD_TESTS=OFF -DMI_BUILD_OBJECT=ON .
```

Error message:
```objc
objc[81759]: realized class 0x7fff807d6088 has corrupt data pointer 0x1044044c0

Start by reproducing the macOS x64 build with the provided CMake command, focusing on CMakeFiles/mimalloc-obj.dir/src/static.c.o and comparing object-file and archive-file linking. Investigate the getaddrinfo() call stack and verify that the object build no longer produces the reported corrupt data pointer.
