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.

Yes, thank you. I did say that "I am currently using ldc-1.41.0-beta1 without issues."

I'm using ldc-1.41.0-beta1 as well on my 2019 (Intel) MBP running Sequoia 15.5. It's working well so far. The Warp terminal app with its built in genAI really helped me configure it properly.
