Overall, gdb is a better debugger for D. -g means D debug info, -gc means pretend to be C. The most portable way to get -gc in your debug builds, add this to the project's dub.sdl buildType "debug" { buildOptions "debugMode" "debugInfoC" } or if you're using dub.json: "buildTypes": { "debug": { "buildOptions": ["debugMode", "debugInfoC"] } } Btw. it seems like I'm using dub v1.1.2 from homebrew: $ dub --version DUB version unknown, built on Jan 16 2017 $ readlink /usr/local/bin/dub ../Cellar/dub/1.1.2/bin/dub I'll test this with newer releases in the next few days, and if situation is the same, I'll file a bug. Once again, thanks man - feels fantastic having a debugger once again! :) Cheers, Relja I maintain the D packages in homebrew, so let me know if you have any problems. homebrew is up to date with the latest stable dub release, so a quick brew update && brew upgrade dub should get you up to date..

Any reason this flag is not included on dub --build=debug --compiler=ldc2? The docs say it is, but they could be wrong. Could you run dub with -v (and without any manually added -gc) and share the output?

You might also want to experiment with the --debuglib settings and/or --link-debuglib for dealing with phobos.
