digitalmars.D - Invalid alignment on macOS with "-g": anyone have seen it?

Hi all,

Is this a know issue?

It happens only with "-g" on a simple hello world

```

Oh boy. I've seen similar problems with Mac on ARM via ldc2: 
https://github.com/ldc-developers/ldc/issues/3864

I thought it was ARM/LDC specific, but looks like Apple's linker is 
getting tighter on what it will allow.

This needs addressing ASAP. Can you file a bug report?

I'm hesitant to upgrade to 13 now...
