DMDFE: ldc2 ../a/bar.d ../b/bar.d Error: module bar from file ../b/bar.d conflicts with another module bar from file ../a/bar.d causes ldc to fail even with -oq (output module *.o's with their fully qualified name) switch, which is supposed to allow this. It did work around about July. see https://github.com/ldc-developers/ldc/issues/1781 this blocks having a sane layout for dcompute.
Cannot reproduce with dmd, unless the module declaration is missing.
This was fixed by https://github.com/ldc-developers/ldc/commit/eb85bc2f75706ea1ae54f5dc1a0345cc41f2f55c
