I just fixed a bug in my personal D hobby project.  After pushing 
everything to github, I noticed that it fails to link with the 
latest LDC on MacOS.  The error I'm getting is thus:

```
ld: warning: alignment (1) of atom 'anon' is too small and may 
result in unaligned pointers
ld: warning: pointer not aligned at address 0x3D2C9 ('anon' +

/Users/runner/hostedtoolcache/dc/ldc2-1.30.0/x64/ldc2-1.30.0-os
-universal/bin/ldc2 failed with exit code 1.
```

This only happens when building the project as a shared library.  
It builds perfectly fine as a static library.  Any solutions?  
Thanks in advance.
