This is the the version of macos I'm using:
Darwin MacBookPro 24.4.0 Darwin Kernel Version 24.4.0: Fri Apr 11 18:28:23 PDT 2025; root:xnu-11417.101.15~117/RELEASE_X86_64 x86_64

I have the following versions of D comilers insealled on my machine:
dmd-2.100.2           dmd-2.106.0-beta.1    dmd-2.109.1
dmd-2.101.0           dmd-2.106.1           dmd-2.110.0
dmd-2.101.1           dmd-2.107.0           dmd-2.111.0
dmd-2.103.1           dmd-2.107.1           ldc-1.32.1
dmd-2.104.0           dmd-2.107.1-rc.1      ldc-1.32.2
dmd-2.104.0-beta.1    dmd-2.108.0           ldc-1.39.0
dmd-2.105.0           dmd-2.108.0-rc.1      ldc-1.40.1
dmd-2.105.2           dmd-2.108.1           ldc-1.41.0-beta1
dmd-2.105.3           dmd-2.109.0
dmd-2.106.0           dmd-2.109.0-beta.1

All versions of the dmd compiler except for dmd-2.100.2 results in a segmentation fault when executed:
(dmd-2.111.0)confuzzled@ambpro Projects % dmd
zsh: segmentation fault  dmd

I am currently using ldc-1.41.0-beta1 without issues.

This is fixed in Druntime, but there hasn't been a new DMD release, yet.

Also, as I learned on discord, the fix was backported to the ldc version in homebrew.  I had to `brew reinstall ldc` and now ldc works again on macos.
