Bug 19503 – lld: Native PDB Error: The entry already exists. The specified module already exists

Created attachment 1720 testcase Execute "dub test --arch x86_64" for attached example. LLD linker will fail with: C:\Users\pc\Desktop\testcase>dub test --arch x86_64 Running custom 'unittest' configuration. Performing "unittest" build using C:\D\dmd2\windows\bin\dmd.exe for x86_64. d-unit 0.9.0: target for configuration "library" is up to date. testcase ~master: building configuration "unittest"... Linking... Native PDB Error: The entry already exists. The specified module already exists Error: linker exited with status 1 C:\D\dmd2\windows\bin\dmd.exe failed with exit code 1. Very often also NOLOGO error is shown: C:\Users\pc\Desktop\testcase>dub test --arch x86_64 Running custom 'unittest' configuration. Performing "unittest" build using C:\D\dmd2\windows\bin\dmd.exe for x86_64. d-unit 0.9.0: target for configuration "library" is up to date. testcase ~master: building configuration "unittest"...

DMD32 D Compiler v2.084.0-beta.1

The PDB issue is likely fixed with a recent LLD version; the 7z archive of v2.084.0-beta.1 still ships with v5.0.1, although https://github.com/dlang/installer/pull/351 was merged 1.5 months ago (upgrade to v7.0, the first LLD version considered production-ready for Windows targets). As to NOLOGO, that's rather strange; it's supposed to be an LLD flag (`-L=/NOLOGO` in DMD command line). The error seems to indicate that the DMD command line (issued by dub) is the problem, not DMD itself. So running dub with `-v` to output the command lines would probably shed some light on this.

Should be fixed by https://github.com/dlang/installer/pull/355 for the next nightly. I will have to backport this to stable.

Thanks a lot! I can confirm, version v7.0 solves the PDB issue. The NOLOGO issue still occurs on every third/fourth try and the dmd compile / link commands looks identical for the cases where NOLOGO issue occurs and not occurs. --------nologo error -------- PS C:\Users\user\Desktop\testcase> dub test --vverbose Refreshing local packages (refresh existing: true)...
