I don't speak English well, so I'm writing this through translation.
Sorry if anything sounds unnatural.
Environment
macOS: Sequoia 15.4.1
Chip: Apple M1 MAX
Problem
When running the binaries from the v0.15.2 release archive, I get segmentation faults:
$ ./dcd-server --version
zsh: segmentation fault ./dcd-server --version
$ ./dcd-client --version
zsh: segmentation fault ./dcd-client --version
What I tried
When I clone the repository and build the binaries myself, the version displays correctly:
$ git clone https://github.com/dlang-community/DCD.git
$ cd DCD
$ git checkout v0.15.2
$ dub build --build=release --config=client
$ dub build --build=release --config=server
$cd bin
$ ./dcd-server --version
v0.15.2
$ ./dcd-client --version
v0.15.2
Conclusion
It seems that the file below in the release assets is broken or incompatible with Apple Silicon:
dcd-v0.15.2-osx-arm64.tar.gz
