--- Comment #2 from github-bugzi...@puremagic.com --- Commits pushed to stable at https://github.com/dlang/druntime https://github.com/dlang/druntime/commit/10afa6944bb3ac479cbcabc5499a86136907b95f Fix issue 18193 - module config is in file 'rt/config.d' which cannot be read (edit) src/rt isn't shipped with druntime's imports, so it can't be imported directly from core.runtime. This PR fixes importing rt.config from a public druntime module by replacing it with an extern definition. To reproduce the bug create a file that imports 'core.runtime' and compile it with: dmd -unittest -deps filename.d The error is: /usr/include/dmd/druntime/import/core/runtime.d(653): Error: module config is in file 'rt/config.d' which cannot be read https://github.com/dlang/druntime/commit/105d4a5ca279316665b3b796bf5ca7d249595caf Add test to the bug 18193 --
